Re: obs disc on 63-66 C10 upper arms?

The later (73-87) 3/4 & 1-ton trucks utilize the same HD bushings as the pre-73 1/2 ton trucks. They do not utilize the 'car' style bushing.
Only the 73-87 1/2 ton trucks use the 'car' style bushing. The later '88-up chassis use the rubber bushings in the 1/2 - 1-ton configuraation.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
