My mounts were relatively new converitble mounts. Nothing odd about my steering shaft or anything. The wierdest thing was the H-pipe I got from summit to match the headers. The driver's side hanger was welded on facing the wrong way. It faced toward the back of the car. No way you could mount it like that. i returned it, they sent me another one just like it. No it wasn't the same one. Flowtech let the "special" kids do the welding that day...N2O88 said:I don't know why you had so many problems billy, were your mounts shot? Running drop mounts? I had no problems with installing them on my brothers vert about 2 years ago, and when I put heads on it later there weren't any problems rebolting them on......and they still look decent and should be good for years to come. About the slip fits, use copper rtv in the slip fit joints, just glob it in there.....sealed up our leaks nicely.
