So, since I'm doing so many other modifications, I decided to just cut the other spring to the same length as the shorter one. This will drop the height about the same as the front did with the drop spindles. It's easy enough to change the rear springs out if I feel I need to but at least this gives me a starting point.

Hi,

I know some of you have faced the challenge of doing without a handbrake when installing a panhard rod setup. I thought about eliminating the handbrake because the car is rapidly becoming a dedicated race car, but really would like to be able to set the HB with engine running for tuning purposes.

As such, I came up with the following solution. I welded some 1/8" bar stock with a 30 degree angle to a 90 degree leg. Then I reinforced it with a 45. It's not done, but looks like it will work and will be safely out of the way of the rod...

Why not convert to a hydraulic handbrake, or just a closing valve? Hydraulic handbrake is allowed for streetuse (at least overhere in the Netherlands) .
Closing valve is all you need on a racecar . You can skip all the mecanical handbrake parts. Automotive Plumbing Solutions Line Lock | Demon Tweeks

Wish I saw this sooner... looks like a better solution.

Thanks.

Tranny Mount

Any thoughts/advice on installing this "race" mount vs. the original style?

The tolerability of a stiffer tailshaft bushing depends to some extent on how well your flywheel/clutch assembly is balanced.

Interesting. I recently had some serious clutch problems as a result of the flywheel mounting points for the PP being eccentric. I think I'll leave the softer bushing in for now and experiment later.

Thanks.

Hope you never actually need it as an emergency brake then ...

There is a reason hydraulic handbrakes are illegal in most countries.

I think that depends a bit on the implementation. If it's set up as a completely independent system with its own master cylinder and calipers, I think it would be perfectly valid as an emergency brake. Some drift and rally cars run setups like that. Of course, if it relies on the primary system in any way, that's a problem.
