Nice to be a part a DART forum, so much good advise is priceless... Here is my issue, I purchased a disc brake conversion kit from Classic Industries. part # MN 5005 with the tubular upper A-arms. The kit is from CPP, I got the A-arm, lower ball joint and spindle mounted and all looked good, then I lowered the jack to allow full droop of the suspension and thats when the problem started. It seems there is not enough travel in the suspension now. It dropped so far that the A-arm pinched the upper ball joint boot and cut it. Just hoping someone has used this kit with some success. its for a 1970 Dart, 10 inch drum to disc conversion. Thank you in advance for any help that may come my way.
