I used a TH400 yoke. It uses the 1310 u joint and will fit if you if you cut it to the correct length.

A drive-line shop told me using a TH400 with a ZF is much the same as a 100K mile used correct slip-yoke. They wouldn't build a drive shaft for a friend knowing it was for a ZF using a TH400 slip-yoke with any kind of warranty. Will other shops? Likely!

A ZF is a 35mm (1.378) output shaft, a TH400 is 1.397 I believe. It slips over but isn't considered correct. Used by many? I imagine

The 5-3615X is a 1350 series joint and 'incorrect' for the ZF drive-shaft. Is the drive-shaft intended for a C4 Corvette or is it maybe intended for something 'other than'? Many years ago I suggested a different slip-yoke and using a 1310/1330 conversion joint. The slip-yoke requires 30mm be trimmed from it.

Many have used it. Application for the drive-shaft I'd think very important!!

Mine has been working for over ten years now. It was recommended and installed by a shop (they only do drive shafts and differentials) that is well known in the local drag racing community. The correct yoke has not been not available new for many years. If you have a better solution please share it with us.

Its for a stock c4 l98 zf 6 speed. And if the 5-3615x is incorrect, then do you know what is?

I'm sure there are others that have done similar! You're happy - that's good.

A Spicer 2-3-10831X needs a 1310/1330 conversion joint and 30mm trimmed from it. Several here on the CF have used this and I'm quite sure Bill B has used it also. Would Bill use/suggest a TH400? I've no idea.

I 1st suggested this years ago and a search for the # would likely show a few. It corrected a balance issue for a fellow in Austria that I consider a very talented individual. This is his last comment regarding his install. He had a TH400 slip-yoke. He had a shaft built using a 1330 front with it and a 1310 rear @ the pinion.

Just ask the shop for a 1310 Spicer u-joint. Do you actually need a slip-yoke? How badly is yours worn. If not real bad I'd look into 'hard-chrome' plating that's used in industrial machine repair. I've never done it to a slip-yoke but if it were a wear of the outer finish I'd consider it.

Ok, thanks for the info.



Bought the car non-operating, knew it needed distributor cap and rotor along with a starter. Turns out it also needs a driveshaft as it is missing. I am supposed to go up tommrow and he says he knows where it is but based off our interactions i am not holding my breathe. If I cant get the driveshaft tommrow then i will nees to source a replacement. Was looking into just putting one together from an ebay shaft sin ujoints and yoke but am now leaning toward the dorman 936-290, which is listed by dorman as a drop in replacement, due to my lack of certainty in finding a yoke and proper fittings for any significant amount less.

There's much about that Dorman that 'hints' NO FIT - Unless it was local where I could put hands on before buying I (myself) wouldn't touch it. Where are you located?

OP - I spotted another thread you started mentioning the cap, rotor etc also missing. Now the drive-shaft seems to be maybe missing. I'd suggest you 'gather your thoughts' and confirm much more regarding car condition before you spend 1¢ more. There's much you need to do before being concerned I'd think with a drive-shaft.
