No problem. Got the Dorman book in front of me, and it sez the following:

1965-1970 front stud w/disc brakes, LH: 610-131
1965-1970 front stud, w/disc brakes, RH: 610-130
1965-1970 rear stud, LH: 610-099
1965-1970 rear stud, RH: 610-186

Also sez:

1971-1972 front stud, w/disc brakes, LH & RH: 610-130

That seems like pretty good proof to me that these are definitely the right (and left!) ones. Wanna bet Layson buys 'em in bulk from Dorman and marks 'em up-up-and away? I find 'em for $1.19/ea at RockAuto.

Headlamp upgrades 'n' stuff in stock, give a yell when you're ready.

Those are pretty good prices compared to what I paid for my NOS ones from CollectorsAuto last year. I think it was twelve CDN for five of them, not including shipping...

Hey Dan - Thanks for the info on the studs. I'll check at my local NAPA with those #s and see what they have to say. I assume that the rears fit both the 7 1/4 as well as the 8 3/4 (which are going in both Plymouths as well as both Darts)

1) NAPA does not have Dorman parts.

2) No, the rear studs are different from the front ones. You want those numbers, too?

Hi Dan if you have the numbers for the rear studs 8 3/4 axles, would sure appreciate it. The clowns who work in the parts stores/hardware, etc around here only know how to look something up on their computers, much less look in a book. Aahhhh don't get me started on that!!!

Looks like

610-099 (LH)
610-186 (RH)
