the lip is on top of the floor instead of under the floor, not sure how much difference that will make in how much everything lines up but it may make a difference in everything you have had to trim.The bulkhead doesn’t look right to me. Not sure why, but something looks off.
I thought the last picture in post #5 above looked odd but couldn't put my finger on it. That bulkhead is going to be slightly higher with it sitting on top of the floor panel - not sure how much, but it will definitely move the bulkhead higher and could be just enough to cause the issues experienced so far.the lip is on top of the floor instead of under the floor,
Samesies..... not issue with my pedal touching the bulkhead. Now my steering shaft was a different story.I had an 2006 SS/SC donor also but didn’t have that problem. I’ll try to remember to take a look at mine to see if I notice anything different.
You helped spark my memory. In addition to trying to persuade it upward a bit, I ended up adding a spacer under the pedal box assembly on the top mount tube. This helped rotate it away from the bulkhead.A bend down would rotate the pedal assembly into the bulkhead.
Same here. I couldn't tighten the pedal box to the frame completely until everything was in place or it wouldn't line up. Until after the brake booster was in place and then I could tighten it all up. It worked out ok in the end though.Depending on how the powder coater moved the chassis around, the mount tube could have been moved out of its original position. I only say this because I saw my powder coater bend my cluster mount tabs when lifting the chassis with his forklift. I'm not sure the mount tube would bend/move nearly as easily, but it's possible.
My only issues with my throttle pedal were lining up the pedal box mounting holes and tunnel interference. I had to fight with the pedal box a bit to get the holes lined up but no trimming was required. On my second or third test drive, I floored it and the pedal got hung up on a tunnel cap rivet. A little force on the pedal arm fixed that before using the 3D-printed pedal extension that moves it entirely away from that part of the tunnel.
