Selling a ton of parts, can someone help determine value?

If this doesn't belong here someone pleaes tell me where to put it.

I just want to know how much I should ask for each part/ as a bundle

My Cobra was Solid axle swapped by the previous owner less than a year ago. I am swapping back. I no longer need these parts, and don't really know what they're worth individually

8.8 from 03 GT, was told it came from a low mile car. 4.10 gears(Less than 8k miles). Had 0 issues, just want to go with a built IRS for my car. would sell with lug nuts

Rear Brake discs
Stock 2001 Cobra front springs
Laser Red 01 Cobra/V6/etc side scoops, missing 1 push pin, all tabs are there though.
03 GT rear sway bar.
Unkown brand adjustable Upper and Lower Control arms(Less than 8k miles)
Eibach Drag-Launch Springs 9310.002L (less than 8k miles) with or without Isolators
KYB Gas-a-just shocks
Pre-axle cut exhaust, not entirely sure but they seem like cherry bomb "mufflers" welded on, pretty loud
Also what would be a fair price for the whole rear end as a bundle? Any and all help would be appreciated, please and thank you!

Update: The brand of the control arms is Team Z Motorsports

Have you sold any of this?

I've sold it all! I still have eibach pro kit front springs available from that post. I have a few more parts now also I'd sell anything particular you're looking for?
