Hi to all you great people

,
I have the option of purchasing a '75 1.9L Opel Sportwagon that has fuel injection. I have only seen pictures of it at this point. The body looks a little rough, but it is supposed to run good. I'm seriously contemplating buying the car to pulling the motor & EFI system and installing it into one of my GT's that needs a motor. After studying the threads I understand that it should bolt in without any problems. I also understand that it has L-type fuel injection. Also, I understand that the cold start injector may hit the firewall in the GT, so some customizing may be in order. Other than that and switching over the wiring and module,
1) what kind of problems should I plan on

?
2) do you think it would be worth the hassle

?
Any additional input would be greatly appreciated.
Thanks a bunch,
James.
