yea im running 1 7/8 stepped to2" primaries. mine are Kooks. he should be producing headers for the trucks. he contacted US and we sent him pics of his headers in my truck so he could use it as an idea to produce headers fo the turcks

 

quick how much fab work was involved to get them to fit?

 

slide them in from the bottom and called it a day but not all fbodys are shaped the same. so becareful

only fab work ill have is custom exhaust cause the driverside kicks out some but nothing thatcant be worked with when doing custom exhaust

 

Checked out the pics from your install, looked like you dented the primaries to clear the frame. Don't think they'll work for me though. Since the driver side kicks out, it probably won't clear my front drive shaft. I'm 4x4.

 

i didnt dent them to clear. that was a mishap when buddy had them. you without the dent it would still clear. but have to remember thsoe are 2" primaries in that area. regular 1 7/8 or 1 3/4 will clear

i also run solid motor mounts
