LCA and Spindle fitment Help

[RAT ROD AL]

I have a pair of standard 67 LCA small U joint , small bolt pattern ,listed for sale.
@Rassnasty82 Has paid me for these and before I ship to him I want to make sure they will fit his car.

He say's he has a 69 Cuda with large Ball joint UCA, 4 piston calipers, Possibly from a 73 Duster "?" -AND LARGE BOLT PATTERN hubs.
Hopefully Rass will join in with more info if needed.
What year did the bolt pattern change ,when did the brakes change , and did the spindles and
LCA change also ? Thanks for any info on getting this lined out !

His description doesn't make any sense.

The switch to LBJ UCA's was in 1973. That was for both the disk and drum cars. Disk cars were 5x4.5", drum/drum cars stayed 5x4" all the way through '75.

73+ disks were all single piston calipers. No 4 piston calipers for any 73+ cars, or any BBP cars, or any LBJ cars. If he has 4 piston calipers with those things they're aftermarket.

67-72 KH disks had 4 piston calipers, but they also had SBJ UCA's and the 5x4" pattern.

The LCA's are the same '67-'76 except for the location of the sway bar tabs. So, a non-sway bar LCA can swap '67-'76.

Lower ball joints are different for almost all of the different brake set ups, even the 9" and 10" SBP drum lower ball joints were different. But they all bolt to the same LCA, you just have to match the lower ball joint to the spindles you have.

So , I thinking my LCA will work with what ever he has. He has to have Small bolt pattern . ( wasn't sure on that )
I also asked him to check to make sure . I was all set to ship to him , but then he said he had large BP , It didn't sound right to me.
Thanks. Hopefully he will chime in here with me !

LCAs all interchange, with the exceptions of the ones equipped with anti-sway bar tabs. With tabs, '72 and earlier are the same; '73 and later are the same. If no tabs, they all interchange.
Bolt pattern changed to LBP in '73 on disc brake cars. '73 and later disc brake calipers were single piston.
Spindles changed with each brake package: 9" drum, 10" drum, and KH discs each used their own spindle design. '73 and up discs and drums each used their own spindle design also (although there was some carryover on 9" drums).
'73 and up used the large ball joint in the upper control arm. Lower remained unchanged.

Ya beat me, 72... I type slooow...

Yeah if it's a non-sway bar LCA it'll work regardless of what else he has.

Thanks guys for the help.

It is possible that somebody cobbled it up with B-body Bendix four piston brakes, BUT as stated above, the LCAs will interchange.

Oh, that's a good point! I forgot about those. Those would have been '67-69? I know in '70 they went to the single piston set up but still had different wheel bearing than 73+.
