Kit was wrong and would not plumb up

Normally easy.

St Joseph MO

Converting my 68 Mustang from manual drums to power disc brakes. This kit looked good but required a lot of drilling and cutting. The brake pedal arm had to be ground at the top to clear the original mounting bracket. The firewall had to be drilled and cut. I had to buy a master cylinder push rod bushing, spacers and a brake lite switch for power brakes instead of manual. Nothing about any of the additional parts listed in the instructions. The worst part however was the kit had the wrong master cylinder in the kit and tech support was NOT helpful in getting me a new correct part. It's been a month and I still have no resolution.
