65386....1 3/4"-1 7/8" Step and a 3" collector. You can get a 3 1/2" collector if you want.
65380.....1 3/4" w/ 3" collector
65385.....1 7/8" w/ 3 1/2" collector

If you are running a stick car, #7 tube has to be moved because of interence with the clutch rod and z-bar.

Must have manual rack also.

Woodro helped me out with the LT1 stuff.

Phil Veldheer put the number on here, on the first page. Call there and ask for either MIke Thomas or my brother Phillip. They will help you. Crisco has the part numbers in his head now.. Thats pretty cool !

I have seen that alot also. My wife has a 98 with a LS1 in it. I know it a 98 cause I looked at the door tag and it was build somewhere around March of 98. She bought it new in 99. It's Z28 that has no options but t-tops. No pwr windows,locks,cruise, nothing.
