Hi I am almost completely done with my 66 ss convertible every thing has been done to it down to the bolt heads, I am having trouble finding the right transmission flywheel cover for it to complete this job, It is a big block with a 2 speed powerglide, I have bought a couple of glide covers for it but they are to narrow, It seems to need to be 1 inch wider for the starter to cover, Does anyone have any sugestions on where to find one, the book shows a part #3831527, I would really appreciate the help, Thanks Don
