Re: COPO 12 bolt carrier ID?
His book has all the anal details. Natural color posi springs rated at 75lb each, stds are green rated@ 50 lbs. 18 clutches. Photos of the posi plates and the holes are round. I talked to him on the phone several times since I sent my boy's engine to him. Wealth of info. Glad I hooked up with him thanks to this site. He was selling these units at the dealer he worked at back in the early 1970's. Say's they are stronger than the Moroso brute unit. Service 234 units do have the large hole for easier spider gear installation.
