I have a '74.5 (11-74 build) with rubber bumpers and dual SUs.
The suspension does not have a sway bar, the stock wishbone arms are not drilled and reinforced for it.
I got a used bar from someone that installed the new variable style bar.
In the box there were down links and the bar as well as a pair of poly bushings.
While I need a few items to do the job:
a pair of 322-110 bolts (no nuts available??)
a pair of the 263-430 mount brackets...
...the wishbone arms need to be altered. With every intention of altering them for the sway bar by drilling two holes and reinforcing the holes with a welded section, I noticed that the bolts that attach the Wishbone arms to the spring pans are a lot closer to the location the downlinks will attach than i had anticipated. Close enough so that if I were to drill through at the locator holes there would not be adequate space for the washers and nuts on the downlinks.
Is this right? There is no way this can work, and if I get the 264-035 and 264-030 wish bones that are pre-drilled for the sway bar it will line up with the holes in the pan and I just don't see how it will work.

Ah.....
Are you saying that I remove the little bolt that is there and the downlink end bolt replaces it just a tad inboard?
When I added the sway bar to the '76 I thought I kept the bolt and added the down link fastener.
Are you sure Keith?

I just installed a sway bar in my 76 (which had none) about a week ago
I replaced the front wishbone arms with the reinforced ones, drilled for the sway bar. The larger hole for the link aligned perfectly with the spring pan.
The wishbone arms cost under 11.00 from Basil Adams and went on with minimal disassembly... about 2 hours for both (I'm old and slow)

What Gary said. I installed an original style sway bar that I got from Glenn here on the site, he sent it with all of the parts but I did have to replace the dog bones to get ones with the proper size holes and reinforcements. I got mine from BPNW I think for $15ea or so. They are a pretty easy part to change and since you have to disassemble the A arm assembly anyway this is a good excuse to replace the bushings. The whole process took me a couple of hours.
