I’ve bought thousands of dollars worth of goods from GBody Parts over the last 20 years & never had a single issue!
Everything was shipped on time & was exactly as advertised . Brian has always been easy to reach on Facebook and responded promptly. GBody Parts are one of my Go To vendors for my...
I ended up using the axle mounting brackets from my HR Parts n Stuff rear sway bar as they were a lot more robust & beefier than the flimsy U bolt & bracket set up supplied by UMI
Could always try a Flow Kooler LS water pump.

Scot W @ GNS Performance offers a kit for a rear frame rail brace
I’ve had mine installed for quite some time & can vouche for how it keeps those rails from flexing….really helps to tighten up the back end of these cars
Caspers’ Electronics should have what you’re looking for
I’d contact John or Justin Spina & see which one they’d recommend

I ended up getting my fan turn on / turn off set points altered on my chip to better suit the 180 deg T stat.
My fans now come on at 188 deg F & off T 170 deg f
Maybe think about sending your chip back & re-burned to suit the new 180 T stat?
Changed over from a 160 to 180 T stat since installing aluminum radiator . The 160 didn’t allow warm enough engine operating temperature . If yours is a race car then keep it but for the street definitely go with the 180
I might have a complete set of used (but original) bolts for you.
Set them aside in my nuts n bolts bin when changing over to aftermarket rear control arms.

Evap-O-Rust Thermocure worked great for me on my Alradco Aluminum Radiator.

Another item worth considering is a rear frame rail brace which will tie the rails together and minimize movement.
Scot W at GNS Performance offers this kit and really tightens up the rear of the frame

Installed a Wilwood adjustable proportioning valve while installing my HydroBoost brake installation.
Works great , plus I now have the adjustability of fine tuning brake bias .
Of course , had to remove the original factory brass proportioning valve in the process
