So after ten years of trying to collect parts and get the m715 back on the road it's done. First official drive on memorial day which I thought was fitting.
350 small block, power brakes and steering. All new wiring and brake system. XZL's.
It's a completely different truck now.
Much appreciation and thanks to everyone on here who either helped answering questions directly or were willing to share knowledge on the site.
First time trying to put up a pic. Sorry if I failed but thanks again!!
