Diseazd , I went with the stock type system because it's just simple and easy. I really didn't want to drop the diff, and while I've heard that installing the RT mount is possible with the diff in place, I've also heard that it's way easier if you pull the diff first. Doing what I did, I didn't have to pull the diff or mess with any of the driveshafts. My thinking is that the original stock mount lasted the first forty years and if I use a tight strap to keep the front of the diff from lifting, I should be able to get the next forty years out of the new OEM lower mount I just put in. And with that in mind...
sweatybetty, Where did I get a new strap? I sewed myself a new one! As proof of concept, I bought some cheap blue nylon webbing at the local hardware store and sewed loops on the ends. I'm no seamstress, so please be kind... Sewed a loop on one end:
Here's how the loops fits over the mounting rod:
In order to determine where to put the other end loop, I installed it in the car and measured for length by looping around both end mounts and removing the slack. If you look carefully, you can see my Sharpie marks:
After measuring for proper length, I sewed the loop on the second end and it looks like this. Like I said, I'm no seamstress. I was focused more on strength than looks:
Wrapped around both end mounting points and installed above the diff, it looks like this:
Summary... Here's all my parts. Old mount stuff on the right, new on the left:
That lightweight blue webbing strap got me to Zcon and back, but it's really a temporary install. It's a thin gauge webbing of unknown origin and specification. Since making the original strap, I've purchased some known quality webbing from McMaster and I will make a second strap to replace it. Here's the better webbing from McMaster:
So I don't have any data as to the longevity of my strap solution, but I can tell you that cheapie blue one has been in there for about a month and is still going strong. I can also tell you that it's doing a whole lot more for retaining the diff nose than my original stretched out crispy factory strap.
