U-Joint Cross Reference Info Needed

[55 Fargo]

Hi all, was wondering if anyone may have an idea on a cross reference or modern match for cross yolk U joints for a 48 Chrysler.

The NOS are very pricey, these u=joints do not look like anything special, but getting a size to match is the ticket.

So if anyone has any ideas, could you please let me know.

I Have thouight of pulling one u-joint off a parts car, then try and match from parts store inventory.

This ujoint can't be this rare......Thanx Fred

Got a pic of what they look like? I think I had to pay about 75 bucks for one for my 46 pickup from Roberts.

Ed, these are the flat end u-joints, 1 1/8 round cups,spicer type.

There isa Guy on ebay selling u-joints for Chryslers, not sure if the entire u-joint is the right size. His are only $27.95

Will go out and take a pic, and post in a few minutes.........

How are the ends held in place? C clips? Bolt on bars? My truck has bolt on bars that are serated and the end cups have matching serations.

C Clips hold the u-joint to the yoke

Thanx Rich, that is helpful, but I really wonder what size it is, that I will have to pull one and measure. There isa seller on ebay, selling Mopar Uninversal joint re-pops, for a real decent price, and if they are the same size, may buy those. As the vintage suppliers want a lot of money for them. My NOS parts Guy up here, may not have the correct u-joint, still researching this........Fred

Chryslers use this type of joint With bolt through ears. Detroit style. They are tough to find. Six and eight cylinder joints look the same but the eight cylinder joints are wider/bigger.

I have a friend in the car club I belong to who restored a '48 New Yorker Highlander club coupe with the straight eight. He bought a six cylinder parts car thinking just about everything would be same except the engine. Wrong. Just about everything is different from brake drums, axles, joints, etc. It is hard finding parts for any eight cylinder Chrysler as most of the parts are bigger, stronger, or thicker.

I just spotted a 8cyl chrysler in the junkyard. Along with about 5 6cyl ones.

Start pulling anything that is different than the six cylinder. Those parts are hard to come by and therefore worth money. Hood trim is longer as is hood, any mechanical parts from the engine, etc.

I think all that stuff was still there too. It was starting to rain so my trip got cut short.

Check to see if you have a truck drive shaft place i your area or ask the guys with modified cars where they had their drive shafts made. These folks should have just about every u Joint in stock or they can make them up using croses and different rollers.

We have a couple here in town, they mostly deal with trucks and commercial vehicles but they can come up with a lot of stuff by mixing and matching standard components.

You might have to pay to 2 to make one but still less than the prices which have been noted above.

Ed, If that 8 cyl. NewYorker has a good exhaust manifold-and I stress good you will be closer to retirement if you can get it off in one piece and market it to the big buck T&C guys. These manifolds cannot be permanently repaired(welded) and they are a delicate manifold and crack in the hidden collector part of the manifold. They are a 3 piece setup and don't easily come apart and should not be taken apart either. They are hard to remove though! Got to pull it to see if it's any good. 1946-1950 are the $$$$ years!
