Default TKX Ques


Anyone running a TKX 5 spd? I have a Yoke question. My TKX output is a 31 spline shaft and I have a 31 spline Yoke from Richmond Gear/via Summit Racing that is sold as fitting the TKX. This Yoke is only going 3/4" on to the shaft. I can see no blockage on either part. Anyone else run into this?

Try removing that seal and see if there's a difference....

I'm wondering how your going to make that style yoke work on a C3 Corvette.

that doesn't sound quite right to me..... my ROD 6 speed went in a lot farther than that.
Is there some obstruction in the way.?

You probably want to the following if that is the equivalent of a Turbo 400 yoke:

Do multiple searches available as kits or individually.... prices are wildly all over the place so don't buy the first one your see.TH400 spline slip yoke GM part number 3930827
U-joint bolt and strap: I got them at a chevy dealer was it was ages ago:
014018700 bolt & 003882979 strap

The tail bushing on my new TKX was very tight also but it will go in.

My 81 has a bolt in crossmember. I'm thinking push the yoke all the way in, insert the rear u-joint which will seat with about a 1/2" pull back. all that's needed should be 1/2 inch clearance to get the rear in. What do you think?
