glendale Posted October 10, 2007 Report Posted October 10, 2007 I need rear window regulators for my 51 plymouth hardtop. I know they have to be for a hardtop only. does anybody know what else they will interchange with? Quote
Norm's Coupe Posted October 10, 2007 Report Posted October 10, 2007 What's wrong with the original regulator? They did make repair kits for them. I found a couple Mopar NOS repair kits at a swap meet a few years ago for about $7 each. Not much in there, just some new washers etc. You could probably buy the stuff at the hardware store. If it's stuck, just fill it full of good penetrating oil (not WD40), but the good stuff. It may free up after that. One of mine was stuck when I bought the car but the penetrating oil made it work like new again. Quote
Normspeed Posted October 10, 2007 Report Posted October 10, 2007 My Hollanders really fell apart on this one. It only lists a rear regulator exchange number for the 4 door models. Looks like you may want to look into fixing yours like Norm mentioned. As long as the actual gears aren't stripped, you should be able to repair anything else in there. Quote
Young Ed Posted October 10, 2007 Report Posted October 10, 2007 Ok according to my 1951 mopar parts book your rear regulators are part #s 1248874(right) & 1248875(left). Those#s are also shown for d42 s15 & c51 converts. It doesnt really show the belvedere that I can tell. Under this 1/4 window section it lists 3 sets of #s for p23. One set each for 2dr sedan, club coupe, and conv coupe. The numbers I gave you are the convert ones which I believe are the same as yours. Now for the other brands that same number shows for convertible and special club coupe. Special is perhaps the hardtop? Also post what is wrong with yours someone may have a fix. Quote
48mirage Posted October 10, 2007 Report Posted October 10, 2007 My book covers '35 to '54. I agree with your numbers and find them used for 49 to 52 across the whole mopar line in the convertible coupe and the special club coupe. Jim Quote
62rebelP23 Posted October 13, 2007 Report Posted October 13, 2007 i'd try the hollander computer at work but i already know it won't go past 65 or earlier. each year we lose a year of old stuff due to software limits! i can't cross reference my falcon or my galaxie now... much less the '52! Quote

That's the problem with the computer books software for shops. They expire about every year and you have to buy new software, then the oldest year is cut off. Friend of mine who owns a shop won't buy those programs just for that reason. He will only buy the books. If you want to save the oldest year though, just print that year off before the program goes belly up. That way you can save the printed copies of the oldest year for later use. I would say make a copy of the software but I believe it's set up so you can't copy it. Quote
62rebelP23 Posted October 14, 2007 Report Posted October 14, 2007 too much going on day to day to run any kind of comprehensive lists, and doing ALL of say 1966 would take 1100-1500 pages. we used to have stacks of proper Hollander Interchange manuals but somebody chucked them some time ago. the old manuals are tough to interpret, even for a Navy Storekeeper! a lot of the information we need is still available from the local Autozone and Advance if you can find a counterperson willing to help you. their computers have much more info than even THEY are willing to admit. i try to obtain old paper catalogs from them when they replace them, some of them have some pretty comprehensive listings for older cars; NAPA brake parts catalog i have is great, it covers all kinds of old/odd cars and the numbers are still current for the local NAPA store! we don't even stock brake parts anymore in salvage; it's cheaper to buy new parts from aftermarket and get good ones than take a chance on salvaged brakes!

Normspeed Posted October 14, 2007 Report Posted October 14, 2007 You can still buy Hollanders books new for a reasonable price. They cover different year ranges. Mine covers 1946-56 and once you learn to read it, it's a good reference. 48mirage found some numbers for me that Hollanders did not list. Like to know more about that reference book. Quote
62rebelP23 Posted October 14, 2007 Report Posted October 14, 2007 i thought i was the only geezer who could sit down with a parts catalog and read it like a novel! i mainly do it in search of better parts for old cars; lots of catalogs have dimensions or drawings/photos of the part so you can see if a more recent, improved version will fit in the same space or bolt up to the same bracketry. i mainly started doing it to get dual line master cylinders into my Falcons a number of years ago, before brake upgrade kits were popular. after that, it was getting better upper control arms, to fit disc brakes and 5lug wheels, and it grew. i learned the hard way on what WON'T work too! and since i'm a sucker for an oddball car, i put a Ford Cortina back together using modified Mercury Capri (first version) parts while working at a salvage yard in Virginia! everything to rebuild a Cortina is still available; IF you happen to live in ENGLAND! talk about a challenge.

Dodgeb4ya Posted October 14, 2007 Report Posted October 14, 2007 1949 to 1952 all convertibles and hardtops-dodge ,desoto, plymouth and chrysler-- ALL use the same rear regulators. They get damaged because the window pivot freezes up and people force the regulator and break (split) the gear teeth section. I replaced both on a 52 Belvedere and on a 50 T&C. Lube and adjust the window well and the regulators will last forever! They are somewhat under-designed for strength. Bob Quote
Normspeed Posted October 14, 2007 Report Posted October 14, 2007 I'm wondering if the gear that breaks might be something that you could pirate from a regular and more available door regulator? Quote
Dodgeb4ya Posted October 14, 2007 Report Posted October 14, 2007 The part of the gear that breaks is the "rack" portion. It`s about a 5" radius section. It`s also pretty narrow. I sold a set to a guy who put them in his car and didn`t free up the 1/4 window pivot and guide track and then broke the ones I had just sold him! They are kinda hard to locate. I am keeping an extra set for my cars just in case I might end up with a broken one . Bob Quote
62rebelP23 Posted October 15, 2007 Report Posted October 15, 2007 i forget where i saw it but i did read an article where a guy actually added steel stock to the sector and recut the worn teeth into it. it was a bunch of labor but the car was hard to get parts for apparently! just another possible avenue to inspect. Quote
Normspeed Posted October 15, 2007 Report Posted October 15, 2007 That's sort of what I was thinking, take a sector off a more available regulator, weld part or all of it in where the other one is bad. Quote
