Peter Caldwell at World Wide Imports can provide replacement lever shocks in 
different performance levels.  Standard, heavy duty and adjustable.  Typically 
he would like your old shocks as cores.  He would evaluate the original shocks 
and adjust the core cost if they are rebuildable or not.  Sometimes the 
original shock mounting bolts would loosen and wear the mounting holes in the 
main casting, rendering them not rebuildable. 
I have the adjustable shocks on my TR3 and they are great.  It's just a bleed 
valve plumbed to the piston bores that controls the flow between the bores.  
Reducing or increasing the flow to slow or speed the action.

     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?
