Well I just discovered that the rubber driveshaft flange from the sc300 and the flange on the LSD are a different size.

what are my options?

is there an aftermarket driveshaft that bolts up?
does someone make an adapter flange?
is there a driveshaft from another toyota/lexus i can swap over?
or is a custom driveshaft in order?

Swap flanges. You need a 35mm axle nut socket.

edit: ok it looks that would work

i honestly did some research and saw some posts about swapping the flange, but after i went and took some measurements i thought the base of the flanges were of different sizes. (the seal is definitely smaller on the open diff)

So i just went and re-measured and they do appear to be the same size.

So i need to order a new crush sleeve and new seal for the auto lsd correct?

can you confirm its 35mm? my toyota service manual for the supra says 36mm

Just swapped my flange a few months ago. Definitely 35mm. 36mm socket will not fit in the flange.

I concur that it is a 35mm and just to swap companion flange like what Shern mentioned.

That's what I had to do. I have a GTE, TT Built Auto, TT Diff.
-SC400 driveshaft bolts to both tranny and Diff
-Aristo Companion Flange on tranny
-I think the SC3 trans cross member worked with the Aristo tranny mount, this part was a pain in the *** and took parts from 3 cars to make work

You could prolly easily switch the diff flanges from TT auto to SC3 Flange, like the others are saying. It's a deep socket I bought a couple before I got the correct one for the Transmission flange.
