[TR] TR6 rear shock mount break

[Tim Gaines]

I have been hearing a slapping sound either under or behind me in the 
1974 TR6 when I encounter even slightly rough pavement, so today I 
decided to sort it out. I thought I had found the problem quickly when I 
saw that the spare tire securing hook bolt had come loose, but no such 
luck. When I finally gave up on simple fixes and jacked up the left rear 
end and removed the tire, I saw that the cross member had cracked near 
where the after market shock mount adaptor bolts on. I did a quick check 
with the Moss parts catalog and that cross member is not available with 
them. So, I'm wondering if this shock mount replacement for the old 
lever shock (I installed a couple of decades ago) was a bad idea and put 
too much pressure on that frame member. It occurs to me that there may 
be some folks out there who have gone through this and can tell me just 
how a fix should be attempted.

That crack shown in the photo seems to be only on the back side of the 
cross member. I have learned some welding skills in the last few years, 
and I have a mig welder, but I have never done anything under a car. I 
really don't like the proximity of the gas tank either. I am thinking 
that my local pro welder would be the guy to call on, but is this really 
something that can be fixed that way?
