Most of us guys (at least the older ones) remember the famous recall that GM had for broken engine mounts which involved the throttle sticking open when the mount broke.

I have an NOS kit #325873 for 65-68 small block B bodies. It looks complete, including an instruction sheet.

I was thinking $15 plus actual shipping costs via Canada Post.

I also have the same kit except for 69 small block B body. It looks identical to me but there must be some difference as it has a different part number.
