take a look at my rear suspension...

[ramair351 10]

i bought this 70 mach assembled like this... what the plate sticking towards the tire and what is the hole for? is it supposed to be there?

[buening 63]

That is for the stock rear sway bar. I thought it was supposed to be behind the axle though, but I could be wrong.

[06minx09 10]

Those plates are for a stock 70 boss 302 sway bar and it is in the right position. The bushing kit goes straight up from the hole into the sway bar which goes back over the axle turns 90 degrees through a bushing mounted on the frame rail, and across in front of the fuel tank to the other side.

Yeah I wasn't sure if they were positioned right. FWIW, all Mach 1s came with the rear sway bar, not just Boss cars.

[Cayenne06 10]

All 70 Mach 1s may have rear sway bars but all 69s do not. My 69 does not have a rear sway bar.

Indeed you are correct, thanks!

here is a pic of the other side.. so this car originally had a rear mounted sway bar on it? why would they take it off? will an aftermarket rear mount one fit right on?

Sway bars don't work very well in drag racing applications and make custom exhaust a little more difficult.

Looks like you have some Delalum front leaf spring bushings :)

 

Most aftermarket sway bars are different and won't fit those, however NPD does have a bar that fits the OEM brackets and is part number 5A772-8A. Its not exactly cheap though.

there is also an aftermarket rear bar, Addco or someone makes it, it is a larger diameter sway bar that uses the factory mounts. It's like a 7/8" rear bar instead of the spindly 1/2" or 5/8" factory rear bars.

[buening 63]

Yep, thats the part I was referencing. Addco 7/8" bar

[ramair351 10]

thanks. i am not sure if i will run a bar after all. i have to get some lowering blocks for the rear end, and i may just take the plates off for now.
