WOLFGANG posted:Well, that is definitely substantial steel back there! Maybe it was modified for another type of engine? A Type4 with OEM cooling would require the crossbar to be moved back a couple of inches (or removed) as its 5-6" deeper. Even a fender brace. Looks wider thn a T1/T4 too -- maybe for a Corvair engine which would be both wider and longer.
I wish I could find who the original owner/builder was. I do have a video of an early owner explaining the shocks air adjustment valve location. In the video I can see there was no lower tins installed, you can still see the ground directly below the motor (same motor I have now).
