Yep, I've started a new project Opel GT before I've finished with the Old Hag. I've also taken in a 1.1 '69 GT that hasn't run in a looong time.
This GT was restored over 10 years ago and while it wasn't an Opelspyder restoration it was a decent job. I've found a few places I think I can make improvements but overall it appears to be a very solid car.
I've been driving the '72 off and on this month already. The fuel gauge only reads from 3/4 full. I discovered in some of the paperwork that came with it that OGTS had 'rebuilt' the fuel sending unit. Assuming that I would only need to work on cleaning the ground a little I removed the sending unit. I was a little disappointed when I found 'stuff' in the fuel sending unit tube. I will reinstall it and run with it for awhile knowing I'm going to have to remove the fuel tank at some point in the future.
