18x9 Rally wheels wrapped with Nitto NT555 255/45R18

It seems i got sent the wrong set for the wilwood rear brakes. The backing plates are not for a chevy 10/12 bolt. They seem to be more for a ford bolt pattern

Check out the link. It looks to me like your harness is intended to be used with a TAC module, which utilize 16 pins. I'm surprised the car will start without this connection.

It looks like the Monte pedal only works with Gen IV engines and ECUs and i have a Gen III, so do i need a Vortec or Vette TAC and pedal?

Thanks

I believe that you are correct. Not 100% sure about that! but I think I read that with a gen 4 setup, the TAC module is not required. I was in the middle of researching all of that stuff, when I came across a stupid good deal on a new a Mast M90 setup, so I removed all of my GM electronics, and sold it all.

After 3 long and painful years, i finally have fenders and a hood on

Floor pans had to be primered again for paint

Unfortunately, the regular hood wouldn't close with the Holley Hi-ram and tall and narrow mounts so i switched to the short and wide ones in the hope it will bring the engine down more but it was a no go.

Trimmed the X-brace on the underside of the bonnet but still didn't help so it either i get a Mid-ram or 2 inch cowl hood like toytech93 did. Im going to go with the Mid-ram and switch over the openings in order to retain the 102mm opening and the NW TB but i got the engine to run, ill try to upload a clip of that

Che70velle 12-23-2015 10:02 AM

Good for you! Upload the clip!
Gaps look good. I was about 3 years in for final metal fitment also, so keep your head up!

Progress is progress. Keep at it and you'll be done before you know it.
