'69 Barracuda T56 swap, floor, cross member

I went ahead and ordered this unit and scrapping the electronic gizmo idea:

Interesting!

So it removes the reverse lockout solenoid and replaces it with a spring detent pin that should require some additional force to shift into reverse compared to shifting into 5th, but not as much as forcing through the solenoid?

Definitely curious about how well that works. 5th isn't exactly a "power shift" kind of gear so a little extra tension should be sufficient to keep you out of reverse, or at least give you an indication you missed the shift before you drop the clutch and go into reverse.
Looking a little closer at Silver Sport web site Magnum kits only warranted for 12 months. It's the TKO and TKX kits that get the full coverage for 3 years. Good thing my clutch and transmission seem to be working well.

Well that's lame. Although to be honest those warranties aren't worth much in applications like this. It's too easy for the manufacturer to say "well you installed it wrong" and wash their hands of it. Unless it's insanely obvious is was a manufacturing defect I pretty much figure I'm SOL, especially doing my own work. It's a little easier to get the warranty coverage when you can point to a "professional shop" for the install work.
