It is no longer necessary to replace the entire upper
your doors to fit as they did from the factory. We
have been able to do this by designing and developing a replacement
upper door hinge pin
and bushing set.
outlined in the GM service manual, replacement of the whole hinge assembly
is quite a project! The factory hinge is actually welded to the door,
so it must be cut off, and a replacement GM hinge assembly attached
with bolts. I have done this job on both upper door hinges on my '82
Z-28 project car. After that horrendous experience, I vowed that I would
never again tackle this job for anyone.
I got my '86 IROC-Z it had some accident damage to the drivers side
which required replacing the left door and fender. I obtained a donor
door from another 86 which had relatively low mileage. Even on this
door the upper door hinge was already worn out. I was not about to also
mutilate this door to replace the entire upper door hinge assembly.
Not wanting to relive my earlier experience, I just knew there had to
be a better way! So I set my mind to the problem, and after much thought
I had two replacement hinge pins and bushings custom made for this door.
Third Gen F-body owners saw my handy work and asked if I could fix their
doors too. This is the reason that I have made some slight modifications/improvements
to my original design and now offer them for sale to other Third Gen
F body owners.
really is a pretty slick set up! It can usually be done in about two
