laef springs?

[Tony Cipponeri]

Hi All, I am trying to order leaf springs for my 1950 business coupe, J C Whitney has them, but they are for the 5 passenger coupe and the sedan, I think they will fit my coupe. What say you. Tony C

I say the business coupe is a shorter wheelbase then the 5pass and sedan. I doubt that makes a difference in the springs but it could.

[Tony_Urwin]

My Hollister's says that '37-'52 Plymouth rear springs are all the same.

[Young Ed]

I don't know about that. When we changed the springs on dads 39 the shackles were a 2 piece thing with a threaded bushing and then the shackle threaded into that. The postwar ones have a reg square type shackle with rubber bushings. And the wagons and converts usually have extra leaves.

My 1950 Mopar parts book shows a different part number for the P19 business coupe than the P20 coupe and sedan.

[Tony Cipponeri]

I was told that the sedans, and 5 passenger coupes have one more leaf then the business coupe???? Tony C

[Young Ed]

If an extra leave is the only difference you might be able to use them anyways.

[Tony Cipponeri]

Yeah, I think I can use them, but I would like to if I can use them before I order them. I would like to be sure. Tony C

It does seem strange but my Hollander's (I mis-typed hollister's before) does show interchangeability for those years. Maybe it just means that they interchange, not that they are the same.

Tony, can you check your Hollanders for spring interchangability for the Chrysler C-22 (1939 Chrysler 6, the Royal, Windsor, and Royal Windsor) - mine look iffy, don't have the car on the road yet to see how they ride, just planning ahead.

Thanks,

I can't be much help there- My Hollanders is 1946-56 edition. Sometimes it show earlier years, like the entry that shows '37-52 Plymouths rear spring interchange.

The book shows '41-52 Chrysler 6 cyl rear spring interchange except Crown Imp. Same springs as the 37-52 Plymouth, 38-52 Dodge 6, 39-52 DeSoto 6.

here's what the listing says:

1 3/4" Wide

24 13/16 x 28 13/16 x (RB1) 1 9/32 x 7/8

I couldn't tell you what all those dimensions mean. RB1 is the Incased Rubber Bushing (looks like 1 9/32, but the print is too small and blurry for my old eyes)

[Tony Cipponeri]

Hi All, I ordered a set from J C Whitney. I will find out if they fit. Tony C

Somewhere I read that the business coupes, as most were sold to salesman hauling samples, brochures, and other stuff in the purpose made trunks had an additional leaf in the spring set, and that some models had an additional leaf in the driver's side set to account for the weight of the driver, who would presumably operating without passengers most of the time.

Why not just take the ones you have to a local spring shop and have them re-arched? Look in the yellow pages for shops that service dump trucks and other big trucks. That's also the place to go to get driveshafts rebuilt and flywheels surfaced.
