TRX Handling Package Question

[HBWaterfowler]

Hello,
I found a ton of information in books, Google, this site about the TRX package; But because no TRX package was the same, there are a few grey areas. But most of those things don’t matter to much.

My question here is about the rear shocks. This maybe not even a TRX upgrade, but maybe we can figure this one out. My rear shock looks to have a coilover setup. It has a shock like normal, with a coil spring slipped over it. It doesn’t look like a current rear coil over, maybe an old 80's version? I'm trying to figure out some details about the coilover. Maybe it's not a coilover, but just a knock off coilover that adds some extra support??

Down the road here, I will be replacing the shocks/struts. I would love to reuse the coilover setup in the rear if I can. One thing I know about the 84 Mustang was, it was the last year of TRX package car to be made. The next year in 85, the GT package was created and some of the TRX equipment was carried over and some of it wasn’t.

Also the 87-93 Mustangs had their spindles changed, control arm, other stuff?
I plan on replacing the front suspension with the 87-93 parts to accept the newer struts, but is the shocks different too? I do have an 7.5" rearend, so the mounting points would be different. But will swapping an 8.8 solve all my problems? The 87-93 upgrade would be a step before a 5 lug conversion from the junkyard.

Sorry, for direct bolt-in replacements there is not much choice for the first years of the Fox chassis Mustang. •Performance struts do not mate to the first generation Fox Mustang spindle.
Solution: swap to 1987-93 V8 spindles (or SN95 spindles) and brakes, and choose struts from the 1987-93 V8 group. See the spindle tech section for swap information.
•Performance shocks do not fit the OEM mounting on the 7.5" axle housing.
Solution: install MM rear lower shock mounts, and choose shocks from the 1987-93 V8 group.

I will go take a picture so you can see what I see.

Thanks Everyone!
