1973 charger top "A" arm bushings

[gunnercharger]

Looking for help, if these offset bushings listed below do not fit a 1973 charger, is there any other offset bushings that will or what can you do to get more castor/camber adjustment, thanks

Camber on a '73 charger

I know this is a very old thread, But I am hoping 74sundance or others will know the answer to this question, I have a 1973 dodge charger that I need more movement to get the castor/chamber adjusted right, I looked at these offset bushings "Moog Front Upper Control Arm Offset Bushing Kit 1960-1976 Dodge/Plymouth Car" that 74sundance listed here, but when you look at the model and years that Moog list under VEHICLE FITMENT it says that they only fit a charger or road runner up to 1972, I talked to Moog online and they say these are not listed for the 1973-1974 charger/road runner models, So my question is, has anyone used these offset bushings by Moog in a 1973-1974 charger/road runner? Thanks for any help

Camber on 73 and up is adjusted by "simply" sliding the UCA outward at the top, after loosening the large retaining nuts going through the "dogbone" between the bushings.
There's a fair amount of movement possible. Much more than the 72 and down cams provide (hence the need for those aftermarket offset bushings).
This is possibly why they changed the design so radically.

Caster is adjusted by the relative positions of the front and rear retaining studs/bolts in their respective "slot".

Note- it's not super easy to gauge where they were set and where you've moved them to. I really wish the factory would have made the large ends of the "bone" flat on the sides.

Yes, I know how to adjust for camber and castor, I just don't have enough adjustment to get set right, and in this old tread 74sundance makes it sound like these offset bushings do work in a 1973-1974 charger model

Collision damage?

The offset bushings fit on the relatively small cam bolts.

The 73 and up dog bone is MUCH larger in diameter.

No Collision damage, the K frame was changed from a small block k frame to a big block K frame from a 1973 BB charger

OK, so you're saying the offset bushings will not work on a 1973 due to the dog bone diameter is bigger, so is there any other way to get more adjustment?

Theoretically, the K frames should have the same measurements other than the motor mount locations, and changing it shouldn't effect alignment adjustment geometry.

Thats what i was told and i don,t think it has anything to do with this problem i am having

The Moog K-7103 upper control arm bushings do not fit the 1973 Charger. 1973 - 1979 B-bodies, and 1979 - 1981 R-bodies use a larger bushing (Moog K-7058) with their different adjustment design.

The following image shows the K-7103 bushing with the K-7058 bushing plus the stock type bushing used on 1972 and earlier B-bodies, as well as A-bodies and E-bodies.:

The following image shows the K-7103 bushing with the K-7058 bushing more closely:

The inner and outer diameters are larger on the later bushing as well as other differences with washers, et.al.

Moog did release an offset shaft, or bar, but not bushings, to allow more positive camber adjustment. This bar could be reversed for more negative camber adjustment, but unlike the earlier separate bushings and cam adjusters, the two ends cannot be reversed for opposing positions.

The following image is from the Moog catalog describing the offset shaft.

Moog K-7105 is discontinued, but might be found.

To allow more adjustment movement, the slots in the support bracket can be lengthened, but minimize material removal to prevent any weakening or too much removal of surface mating area at the support bracket adjustment bar bolt mount. The following image shows the support bracket and slots with the other suspension components:

Chrysler released a package in 1980 to allow more positive camber adjustment on affected 1973 - 1980 models. Lack of enough positive camber adjustment could occur with possible frame sag when these cars were still relatively new, although it was more of an issue on F-bodies. The package consisted of two shims to place under the support plate to move it outward allowing more positive caster adjustment. This will lessen negative camber adjustment and alter caster adjustment range.

The following images show the technical service bulletin (TSB), describing the correction package:

Interesting.

Looks like those could be made relatively easily.

Thanks for taking the time to post all of this, This is very good info and This is what I was going to look into doing, looks like the spacers may be 1/4 or 3/8 thick

According to BudW, who made the drawings, the originals are ¼” thick steel.
