Finished up the front disc brake swap using 15/16 master cylinder and lines from Dr Diff. Calipers are for '76 large bore size. At the same time, I removed the power steering unit and installed a manual box and column shaft from a 65 Valiant. Did a complete front end suspension rebuilt with all new bushings, V8 torsion bars, and installed the V8 steering center link. Also replaced the sagging rear springs with 5 leaf, 1" taller than stock springs from ESPO. Note the sidewall rubbing markings on the rear tire sidewalls from before I swapped the springs out. All clearance is good now. Haven't adjusted the front torsion bars yet so sitting slightly high but I'm not going to adjust until after the 5.9 goes in.
Up next: taking out the 170/trans and power wash the engine compartment to see if I can remove those other two layers of flaking paint to get back down to the original color.
