To all:
I'm still fiddling with the repair to my right front upper wishbone
support bracket. I thought I'd let the list populous know I have
"designed" reinforcement plates to close off that open box which
serves as the chassis support for the upper wishbone fulcrum pin.
It's basically the same idea as "boxing in" the differential mounts
I've provided a large opening for access to the brake line. On my
TR6, the 'nuts' which secure the upper wishbone fulcrum pin are
welded to the inside of that box, so there's no need to access them
with a wrench. Some may not want to do this if access to these nuts
is necessary, as I gather that on earlier cars (TR2, TR3, TR4) the
nuts are not captive.
As I've described, the part of this 'box' to which the fulcrum pin
bolts has separated along the rear edge, where the weld has broken.
The crescent shaped cut-out in this plate, which fits 'round the back
of the shock tower has separated from the tower as well, and is
lifted upward about 1/2 inch. Bad news. Also, there is a crack
propagating at the forward, upper corner of the box (directly above
where the brake line passes through the box).
As one who would prefer that the front wheels remain firmly connected
to the chassis while driving, closing off the open side of this box
once the other parts are brought back into proper alignment seems
prudent. I will be adding these reinforcements to the other side as
well, although everything appears to be intact on the driver's side.
Anyone who would like to see the drawing for these plates should
contact me off-list and I'll e-mail them to you.
