Do they fit with stock rear suspension? 8-1/4 rear end?
On a 8" steel wheel?
Further
my headers are a PITA to take off the driver side routes under the steering and there is no way the big old starter could be removed, I assume it's a older long tube design.
They are in bad shape and I think I have to replace them
So what SB header does clear a 74 duster with power steering ..
Long or shorty headers?
No guess work
