Hi Folks,
I just got my frame back from an outfit in Santa Clara,
Amac Fabricators. Amac used to build racecars but recently
got into the business of fabricating kiosks and displays for
trade shows. They still do small automobile related jobs
if time permits, if you can carry it in the door, if its
spotlessly clean, and if the work is highly defined and
bounded (no ill defined dragons wanted). Why am I telling
you all this? Because Art and Ted at Amac do fantastic work.
They fixed me up tremendously. They welded in the trailing
arm frame sections (bought from Auto Rustech), installed the
front control arm re-enforcements, boxed in the differential
mounts, braced the top of the differential carriers (front
and back diff supports), welded on another muffler mount, and
added an additional frame support beam just ahead of the
semi-trailing arm sections, connecting the outer frame rails
to the inner rails at the crucifix. This was done to triangulate
the frame somewhat, and because I probably lost about .010"
of metal thickness on the outer frame rails where the body
mounts due to surface rust on the inside. When they opened the
frame a large amount of dust and flakeyness came out. I'm
going to have the frame sandblasted and painted with hamerite.
I don't know what to do about surface rust on the inside but
I'll probably oil it or waxoil it. Someone mentioned a 2 part
foam that comes in an aerosol can that, when mixed, expands
tremendously, does not absorb water, and if injected into the
frame rails should seal out water and other contaminants. I
have reservations about using this stuff though. It's sort of
like the insulation people inject into the walls of old houses.
Anyone have any experience with anything like this in automotive
applications?
