I'm trying to piece together a 2wd 4L80e and a NP205. There's a couple options I have. One option (thanks sweetk30) is a custom adapter/spacer between the 400/205 adapter and 4L80 trans. This would work perfect but then I still need a figure 8 adapter which I don't have yet. The other option is to purchase a complete custom adapter from Advance Adapters for $300 that will fit the 2 together. This would save me from buying the spacer and 400/205 adapter and make it shorter. The only thing is I would have to do is cut off 1.5" from the 4L80's output shaft leaving 1.5" of spline left (32 spline). Is 1.5" enough??? Also, can someone tell me how far a 32 spline male shaft can go in to a NP205 input short shaft? I don't have my 205 back from the shop yet.
