Hey Bob,

Fletchers car had the cross brace modified, as I remember with a BFH. You
could remove it and take a bit out of the rear section of the tube, then
weld in a plate so it looks factory. Not certain you want to mess with
moving the rack forward. Fletchers motor had a gilmer belt drive for the
w/p and sump pump
