There was a guy in Orange california that customized and shipped several of them to Japan during the van craze 10-15 years ago - there was some real cool ones I'd see setting there waiting to ship out - looks like you got a cool project going.
Thanks for the comments guys. I just acquired a new set of bucket seats for the front out of an exotic car that shall remain nameless. also decided on the Ridetech parallel 4 link with shockwaves for the rear so I can mount them inboard to make room for mini tubs.
I'm thinking of an LS block out of an escalade or tahoe for the power plant and and mating that to the existing 700r4. Also check out the new front seats I just got for my project.
