Bolts to nuts

[Don G 1947]

Anyone know when Mopar went from lug bolts to nuts? I have some 10" drums with studs and nuts I am trying to put a date range on.

Thanks,

Don

The newest iv worked on is a '53 Plymouth and it had bolts, my '40 has bolts, and the '30 has studs.

And some dodges had studs. So you can't really put a year on it.

Ok,

Here you got the 39 Dodge that I had as a parts car had the studs on drums for attaching the rims to the axles. My 1939 Desoto use bolts that htread into teh drums. So even back in to the 30's they were still using the combinations. I know the 39 Chrysler/Desoto used the bolts and the 39 Dodge/Ply used the lug nuts.

I also know that the 38 desoto drums could be used on the 39 Desoto so they used bolts in 1938 for Desoto .

The guy I bought my 36 engine from had a 36 Dodge that had studs.

My 37 and 38 Plymouths all use bolts to go into the axle/drum.

Dodge often has the lug nut and studs compared to hte Plymouth lug bolts..I cannot remember the cut off for the bolts..but the last year for LH thread was 1970..I was thinking the 61 Belvedere had them, same style universal joints...and the e-brake was still a seperate drum on the transmission..

Yeh, its interesting that with all the good engineering that Mopars had they did have a fine selection of things that, whilst they might have been great as engineering methods they were a PITA to work on/repair......in no particular order my bugbears are.......ball & trunion uni joints, tapered axles, wheels attached by bolts instead of studs........these are my personal dislikes, lol, feel free to add or subtract as you wish...........lol........regards, andyd

Andy..how many other driveshafts have lasted as long as the ole ball and trunion, many are still original to the cars they wee installed....and they are the very forerunner to todays CV axle...personally I think they speak volumes..as for the wheel bolts..still be used today in Europe by the thousands..want to love your car forever...work on a VW Rabbit..

So, I have some rear drums I want to sell on ebay that have right and left threaded studs and a flange plate that the studs pass through. Would it be accurate to describe them a pre 1970 Mopar drums? Don't want to mislead anyone.
