Some suspension and brake questions

OMM from what I understand, there were 2 types of drum setups from 73 up.

9" SBP smooth drum which used SBJ UCA and older spindle I am assuming from 63-72

10" SBP finned drum which used LBJ UCA and special spindle made from 73-

I got one set of arms off fakebook off a truk lagoon rusty 74 slant sux duster with 10" finned SBP drums. They are BBJ

The other set of BBJs I got out of my local wrecker yard. It was also a 74 valiant slant sux with 10" finned drums.

Wheel studs on the valiant were also smaller than the 1/2" studs on the 5x4&1/2 drums. I think they were 7/16" studs

I was just over at Todds My neighbor working on the Barracuda. He worked for me years ago tearing these cars apart.. He said the finned drums were small bolt pattern. I asked him about the uppers. He said he don't know we just scrapped them all because they didn't fit any 340 cars.
The way you told me was at least professional. I stated at first from what I remembered. I learn things on this site every day. But I also provide info to many. I said right from the start from what I remembered. I never know what to believe with 72bluNblu because of things I know he is not correct about. So what ever he says I take as him just being a smart ***.
