don't know if you fellas can help.
The 9" Art Carr convertor has a 3 bolt mounting,kind of like 3 bushings are welded onto the forward plate. The convertor attaches to the flexplate with 3, 3/8 X 1-1/2(or so in length) bolts and nuts.
The question I have is this, there are 2 washers used as shims between the flexplate and convertor's welded bushing(s) and I don't know why? Combined the shims are .95 thick. And it appears it's to move the convertor rearwards on the input shaft of the trans. Now, there seems to be plenty of spline length not warrant these shims. Maybe it's to shim the convertor out from the crank's flange.
But, because of the splined input I think the convertor is wanting to walk backwards on the input shaft under load and bowing my old flexplate (it looks bowed backwards) and causing the incredibly loud starter noise.
So...are these shims required? Do I need more to push the convertor back on the trans input shaft more?
Is this typical for an aftermarket convertor? here's some pictures of what I'm talking about.
