The long axle may be done this week..? In the meantime, I got to work on finishing the interior as well as working on the low-profile trans mount. It's going to be a bit stiffer than a normal rubber mount, but that is sometimes what you want.
Here is the first test fit. It's hard to see in this pic but there's a bit over a half-inch of space between the support plate and the subframe rail. The white paint is primer for covering the bare metal after cutting off the auto trans mount base.
