Cover!!!...WE dont need no stinking cover!! I just drive back and forth across the yard, and the flywheel cuts the grass real nice!
With a little fabrication skill, the cover from a 59-63 dynaflow can be made to fit on the '65-'66 GS manual transmission flywheel housing. I did that for my car and it looks just like an original. If you get your hands on one, you will see how easy it is. If I had one, I would put a picture on for everyone to see--anyone out there have one they could take a picture of and show??
I had to scour the salvage yard to find the one I used. As many of those things as they made, shouldn't be too hard to find someone on here that has one. One other important point--make sure it is off of a dynaflow for a 364-401 engine. One for a 215 or v6 engine will not work.
