I got my new driveshaft Friday. They did a nice job on it.
Before I install it, I decided to fix the parking brake bracket problem. This first picture is of the parking brake bracket with the driveshaft installed. There is about 1.5" of clearance between the driveshaft and the bracket.
This picture is of the bracket with the driveshaft removed. You can see that it is centered in the tunnel. This allows the high point of the driveshaft to come into contact with the low point of the bracket. There is some aluminum from my old driveshaft stuck on it where contact was made.
At this point I removed the bracket. I used a cold chisel and a pry bar. An alternative would be to drill out the 4 spot welds that hold the bracket on. The bracket is located just under the back end of the console by its mounting bracket.
I then cut the bracket in half longitudinally and radiused the inner edge for additional clearance. I then drilled 2 holes per side for mounting bolts. I thought about welding it in but decided if I need to make adjusments, bolts would work better.
The transmission/driveshaft tunnel gets taller and wider as you move toward the front of the car. In my car at least, there seems to be less room between the driveshaft and the passenger side of the tunnel. I took what had been the driver's side of the bracket and flipped it and mounted it in the top and side corner slightly more toward the front of the car than originally installed. You will need to remove the console and the carpet from the area where the bolts come through. I cut a 1" or so slit in the carpet and got the hardware in that way. You won't see it because it's under the console.
In determining this location I took into account the length of the parking brake cables and driveshaft range of motion. It appears that now the driveshaft will hit on the floor pan just forward of the rear seat before it will hit the bracket. This morning in an off-road place I can do such things, I pulled a couple of 5k holeshots to see if the bracket will contact my steel driveshaft. It does not appear to have made any contact. I'll check further when I get home.
When I had the steel shaft next to the new aluminum one, there did not appear to be any difference in diameter. I don't know if the same is true for the FRPP driveshaft since I no longer have it.
The other interesting thing I learned was that the yoke from a Ranger M5OD fits into the T5 transmission
