Stubs units for T56

Rob, would you consider making the output units from the T56 to mate with my CVs?

I already explained there is a company that makes T56 output shaft to 930 CV conversion.....
IT is UNNECESSARY but The Driveshaft Shop carries them....
Part# 108-GM-I-42

ALL YOU NEED IS A type 2 CV to 930 CV adapter for your outer stub shafts.

Then all you do is figure how long your 930 aftermarket axle needs to be to insert into the FACTORY C5 output tri-lobe. It is 28 spline and matches a 930 axle spline. The inner race from the tri-lobe is exactly 31mm wide, so I cut a 31.2mm width between the CV clips. I've done 8 sets of 930 axles this way for the 928 6 speed conversion including the Enigma V12 and Just Peachy's LS3 Z06 swap with over 500hp.....

Someone on GT40 site was already making the CV adapters at one time, but I cannot find them, so I'm making my own. I can make an extra pair for you if you'd like....

Rob, i will take a set please PM me with cost and paypal info. Thank you.

I will start these next week. The print had called for 1045 IIRC, but I can't get that in a small piece locally, so I'm going to make them from 4140. So about $200/pr

Rob, please send me paypal link.

Sent PM.Luckily I found 1045 in a short piece, so I'm going with the print spec.

If anyone else wants a set, I'll make them for $225 pair and you can send me 930 axles and I'll cut grooves for $50 and send back.

On the 944-Vette trans swap, they will be somewhere around 17- 19" so measure 3x then order.

I'm finishing the lathe work and will drill/tap next.....

Rob,they look good, just another fine product from you.

I should be shipping yours Thursday Kevin. You will have to determine the exact length socket heads to use for m8 x 1.25 bolts going into 944 stub shafts....

As a side note, these particular adapters don't work on ABS hubs. There needs to be another 1/2" or so material added to the thickness were they bolt on to the stub shafts as the ABS ring has a smaller ID....

Rob, so i will have to change my stub units as they have the ABS ring. I figure a basic turbo unit will work.

I had an early alloy arm without the ABS ring on the stub shaft and the adapters bolted right up. I have on hand an 87 arm with ABS ring and you can just cut it off if you're not running ABS....

Rob, thanks, thats what i will do.

Rob, the adapters landed, Very nice product. Thank you.

Ive been MIA for a while, just saw these... they look like a great solid piece!

I designed my own over the last few months for my ABS hubs and they look pretty damn similar to these. I made several versions with Inventor, then 3D printed full size pieces to test fit until I was happy with it. Slight changes may still need to be made, but overall it appears it will do the job.

The pictures arent the best... but I will post better ones once they are made in steel. The orange piece is a 3D printed 930 CV I used for mock fitting. Blue is the adapter...
