does anyone know if a aod out of a mark vii will work in a 90 gt.also will a c4 work and what does it take to make it work?

Either one will work. The C4 just requires a bit of modification on the transmission cross-member under the car. Then, if using a C4, you can modify the AOD shifter and cable to work on the C4. Not sure how to get an automatic valvebody to work according to throttle on the C4 as it does on the AOD though... you'll want to make sure that's all working correctly or else just get a manual valvebody. I like them better.
