[TR] Mounting a Body Tub to a TR4A Frame

[Brian Induni]

Jerry,
I removed the body from the frame of my 4A and noted the shims/pads that
were in place. Turns out (on my at least) it was the same all around - a
pad/metal shim/pad set up. I didn't have to do any major metal replacement
on mine and when I re-mated the tub to the frame I just matched the original
setup with new pads and shims. I did have to adjust a bit to get the hood to
close properly, but the fenders and doors didn't seem to be affected by
this. I did start on the major floor mounts and alternated one set to the
front - one set to the back. Once I had gooped enough silicone sealer in the
bolts and holes, I snugged everything down like tightening the heads bolts
on an engine - a little bit in rotation.

For what it's worth, I used TRF's body mounting kit and that made the
re-mating a breeze. I suggest using new pads and shims and not over thinking
it too much - rest assured the factory didn't! :-)

Almost guaranteed you'll need to shim the doors anyway.

List,

I am replacing the old rusty body tub with a rebuilt tub from a great donor
car. The new tub required the left floor to be replaced and the from and
rear
valences replaced. The welding was done with the body tub on one of the TR6
shipping mandrels that were furnished with new bodies sold by TRF and
others.
These are the same mandrels that were used to build the new TR 6 bodies.

The doors from the newly rebuilt tub were not removed so I have a good
reference to start with as far as door gaps etc are concerned.

I'd like to know from someone who's done this the correct procedure for
placing shims and mounting pads to secure the tub to the frame so as to
maintain panel alignment etc.
Do I mount the fenders, hood and trunk lid before securing the body leaving
it
in it's static position and then shim the gaps? Do I start with the floor
mounts and work to the front and back?

I don't have any shims placed now, and the tub is just sitting on the frame.

I'd appreciate some guidance fro someone who's done this successfully.

Thanks,
JVV
