Bill Miller,
I might have an interest in the 026G after I look and see what's currently in the motor.Is your spare new or used? Everyone, In my pile of well used spares I found 026109101G and a 026109101A. I haven't found specs to see what's the difference ,but the Techtonics site lists the "A" for 85-87, two engine codes only.They also list a G-grind hydraulic cam, part 049109101GH and it's distinct from the solid version for a Rabbit GTI.This appears to be a VW part number ,as they list the Techtonics cams under a different numbering system. Given what little I know at this point, it would appear that the 026G and 026A are both legal, depending on the engine code in the car, but the 026G is not the same thing as a G-grind hydraulic cam.
