L98 TPI Parts - Everything But The Block!

I spent last year rebuilding my engine (amongst other things) and decided to go the sniper efi route. I saved most every component from the original engine as I replaced various systems in the process. Below is a list of what I'm selling, and I also have a google drive folder link with pictures of all items. Note - I live in the Denver, Colorado area but can ship as needed and will work with you to set a fair additional cost for that.

"donor car" is a 1989 Trans Am GTA with the 5.7 L98 TPI (had been upgraded to 383 stroker 20k miles ago)

Feel free to text me at 7twozero - three3one - 0ninefive8. I am happy to give more details on specific parts as desired.

Do you have the A/C box that mounts on the firewall where the evaporator mounts into? I need that whole box.

Still have some parts left? Was this a Serpentine belt or vbelt setup for the accessories?
