Hello all! I'm new to this site and new to Opels. I recently bought a 1972 OpelGT. It took a few days to get it running but once it was i drove it about one mile before i realized that the tranny was done. I knew i was going to have to do a swop. So i thought i would convert it from an automatic to a 4 speed manual. Just for fun and a challenge. Just wondering if anyone has ever done this before and if anyone has any tips? Also i was wondering about fuel systems. When i got my opel it had a 2bbl carb and thats about all i know. I also got a spare 2bbl weber with the car. I was wondering which kind of carb would be the best? Should i even use a 2bbl? What will run the best?
