[Healeys] Top Trunnion Kit

[David Nock]

These originally were adjustable. But the manufacturer changed the cap 
part of the assembly, and made them a little thicker. Thus making them 
non adjustable with the shims that they supply.

We have shims available to make the kit so they can be correctly adjusted.

I informed them about this about 1 1/2 years ago. I was told that i was 
the only person that was having a problem with the kits.
