TH350 yoke

I'm working on a chassis built in the sixties. It had a SBC with 4 speed coupled to a GM rear end. I bought it without engine and transmission. It had a drive shaft and I got Ujoints for a '60 Chevy which fit the rear end and driveshaft yokes. I have a TH350 and the tranny yoke is wider spaced so the U joint doesn't fit. Is there a different yoke available or do I have to have the drive shaft redone? I know someone has "been there, done that" so please help. This project was started years ago and I finally get moving on it and plan to fire it up, fill the transmission fluid, get it on a trailer and take it to the exhaust man the by first of the week. Please help while I'm getting to work on it!

Sorry that I can't talk bowties but, I'm sure someone will be along who knows what you need! Good to have you here and good luck with your project! After 11 years I finally got mine "on the road" so I know your pain there! LOL.. Oh, and we love pictures round here.. hint / hint / hint ! 8-)

so you need what we call a inside to side clip u joint the u joint clip on the outside over all is shorter and the inside clip is longer . this type of joint is not hard to find it.s more or less a joint to use for matting old 60s to newer 75 newer parts same joint used from chevy to small yoke ford rear end

what i did was buy 2 differnt u joints. one for the year of my rear and the other for the year of my tranny. fit great.

They do make that U joint. I have bought them on many ocasions for GM to Ford rears. Don't recall the # but if you an't find one I'll look see what it is.

Thanks for the input. I just came in and have been trying to locate the dual width U joint. no luck so far so if someone knows where , I look forward to hearing you. Thanks for your responses. I'll post pictures and welcome any input.

good parts guy ? i do not have any listing good counter guy knows what joint you need if you say old GM to newer GM outside clip to inside clip

Awesome! now that makes sense, inside and outside clips! I have several local parts guys to check with. I'm learning how to upload and will post overview photos. Thanks again

There are 2 different sizes for most U-joint applications. One is the standard 1310 series which is the smaller bearing and the 1350 ,which is bigger and used in most hi-po applications. They are also journals that have 1310 on one side and 1350 on the other depending on the end yoke on the rear and the yoke which is on the end of the driveshaft. Check out Dana/Spicer

I think this Neapco 2-1153 Conversion U-Joint 3R to 1350 may be what you need? You might check with Inland Truck Parts if you have one near by - they generally stock most every u-joint combo made.

I believe the # you need is 434 Precision, brand

Just installed a Spicer 5-134X U-joint. The 1310 and 1350 were both discussed at the parts counter. The first one they brough out is for a GM driveline to 9" Ford rear end. The caps were too big for my TH350 yoke and another guy came over and said this was the one for GM old drive shaft to TH350 tranny. It fit and in spite of current drizzle conditions, I'm headed out to drive to install. Going to exhaust man tomorrow afternoon!
Thanks to all and all your suggestions. I knew there had to be an answer and as usual I learn new perspectives on a problem.
