Thanks Andy. These are 2” headers and it’s straight as an arrow from crank crank centerline to rearend pinion nut .
Pretty tight on header opening on passenger side trans mount as well but I think part of that is the mount bushing is new ( red poly ) and seems to have pushed trans up a little higher than the bushing I mocked up with - lesson ? Mock up with exactly what your using- grin.
Next : will you be selling those front spring hangers in the future?
