I have the Rod Bower ram air parts and am trying to fit everything using the RSA 5 fuel servo. One problem is the studs on the engine are too short for the angled shim he provided between the engine and the top of the RSA5. Have others found they have to change the studs on the engine to make this work? Alternatives? I have an old/used engine and my initial attempts to remove the old studs have not been successful. Also, the fiberglass cowl mod is a bit too shallow and needed to be modified. I would like to find out how others may have solved these problems.
