Hi
I would like to transform my Rally-Prepared GT 1900 into a Group 4 RaceCar! (In order with Apendix K for Historic Racing in Europe). Due to the fact that I do not have much time to go Rallying because of to much Circuit Racing.

I am searching for Information on Period Group 4 OPEL-GT's as the Steinmetz, Irmscher, Conrero, ...) as well as for the Specialpart, as:
- Schwedenkopf (Crossflow)
- Limited Slip Diferential
- Sport's or Racing-Gearbox
The aim is to beat up some Porsches 911 in the European Championchip!
Thanks for any Help!
