The one with three triangular brackets that go through the body (likely the one you looked at from Moss), A bracket that bolts to the body with no frame attachment, and a single plate bracket that bolts to the lever shock mount.<br><br>Also watch for feedback on people that just get the lever shocks rebuilt with a heavy duty rebuild. If I was starting over, that is probably what I would do.<br><br>A sample of the three plate design at Moss is 670-128 - see <a href="https://mossmotors.com/rear-tube-shock-conversion-kits">https://mossmotors.com/rear-tube-shock-conversion-kits</a> - the Monroe shock version for the 4A is available. They have an article at <a href="http://www.mossmotoring.com/tr6-tube-shock-conversion/">http://www.mossmotoring.com/tr6-tube-shock-conversion/</a> It looks like a sturdy design, but takes significant effort to install. Read the instructions from their website.<br><br>I do not recommend the bracket that just bolts to the body without a frame attachments.<br><br>I used the single plate version because it was much easier, but this design leads to flexing of the frame cross member and cracking of the frame, including mine. See the 0091, 2217, and 2218 images attached of other people's cars discovered at a local club tech clinic. If you have this design, I recommend you check the frame cross member regularly. If you have the rear spring out for any reason, run the trailing arm through its full range of motion and you will probably see the top of the shock mount move front to rear.<br><br>After having my frame cracks welded, I built a new version of the single plate design available from some vendors. I extended the top mount for the shock back about two inches and added two braces. One is a length of 1" angle iron that goes between the two shock mounts near the top of the bracket, just below the body to side to side stability. The other is the more important addition and goes from the top of the shock bracket rearward to the frame at about a 45 deg angle. This one stops any front to rear motion of the shock bracket. Unfortunately the car isn't easily accessible right now and I can't find my pictures.<br><br>Below is an item I wrote 20 years ago or so. The 5-6025 kit is the single plate design that in my opinion needs at least the added bracket from the top of the shock mount to the frame.<br><br><o:p></o:p></p><h2 align=center style='text-align:center'><span style='color:black'>Tube Shock Conversion Notes<o:p></o:p></span></h2><p class=MsoNormal><span style='color:black'>Notes on my TR6 tube shock conversion:</span> <o:p></o:p></p><p><span style='color:black'>> Would like to know if anybody on the list has any knowledge or experience with<br>> the shock conversion kit that v.b. sells as part # 5-6025.

initial;text-decoration-color: initial;word-spacing:0px'><span style='color:black'>I put similar brackets on my car. They are the easiest design to fit, taking about 30 minutes to install. I purchased my brackets from someone who made them for his car for $40. I bought the shocks from Pep Boys for $12.95 each. The VB shocks must be pretty good to command the $189 price tag. My driving can often be aggressive, especially at autocross events (2nd place in class at the Moss festival and first overall at Triumphest in 1998). The cheap shock seem to work fine for me in the rear, though I may just not know any better. The PO put Koni's on the front.<o:p></o:p></span></p><p style='normal;font-variant-caps: normal;orphans: 2;text-align:start;widows: 2;-webkit-text-stroke-width:

initial;text-decoration-color: initial;word-spacing:0px'><span style='color:black'>Disadvantages of this design:<br>- When the car is in the air, the limit stop for the trailing arm travel is the tube shock. I had a shock fail after only a year (exchanged for free replacement). I think the other one may also need replacement, as there's oil on the tube. This tension is transferred through the shock to the bracket, at a slight angle, torquing the frame cross member that holds the shocks and rear differential mounts. I mention this because I just discovered several broken welds including both rear differential mounts and the crossemember to frame connection near the right shock mount. The car had the differential reinforcing brackets installed for the DPO. I don't know if the shock conversion caused this, but I think it aggravated the problem. (Any comments on this from others?)<o:p></o:p></span></p><p style='normal;font-variant-caps: normal;orphans: 2;text-align:start;widows: 2;-webkit-text-stroke-width:

While looking through my Moss catalog I noticed the kits for replacing the Armstrong shocks with these brackets that you could mount shock absorbers to. But the kits are NLS. No Longer Supplied. I was wondering why the kits were discontinued. It could have been that they caused damage to the frame, or just didn’t work.
