There was no assembly manual for our kit. We did get a manual but it was for the four cylinder car (different engine, transmission, suspension, brakes etc). The only thing we used the manual for was the wiring for the guages. For the four cylinder car, the manual would have been pretty useful. I also think he did an update that is MUCH improved over the one from 5 years ago.
The kit arrived with all parts as agreed. We did have to ship the spindles back but they were replaced with the correct ones. There were assorted fitment issues as our car was the six, not the four cylinder. Those issues included the firewall and the headers. We (meaning Steve) fabbed parts to correct those shortages.
A real good person to talk to about the 4 cylinder kit is Aaron Aslanian on spyderclub.com He has a nice well sorted Thunder Ranch that he built.
The question you really need to ask is "Would you buy another kit from Thunder Ranch?" And the answer is YES!!!!!
