72 longstepper, don’t let your age stop you from doing things ! I’m going to be 65 this year myself. I have friends in their 80’s showing me up all the time ! One is over 90, still living in the boondocks bye himself, and he teaches me stuff every time I visit him. Good luck on your project, I will be watching because I have a leafsprung 71 GMC that I would love to lower a bit. It has heavy duty rear spring option in black...
