Mark Williams 32 spline input shaft for 4l80e conversion. Any body not ready yet for it and can sell it now!! round 2 for the next batch in at 10 of 12 needed so it wont be long to get replacement. What you have ???
I have one laying around. I think it's even one of the 300m ones that were made, but unsure. I bought it second or third hand, but it's in perfect condition. Sounds like you are in a rush and I always like your builds so...
You can have it, send me an address and I will try and get it shipped on Monday.
