What size sway bar or bushing replacement?

[UKPlymouth]

Guys,
There are two sizes of front roll bar diameter listed for my 73 Roadrunner (340 car)
13/16 or 15/16?
Summit has both listed for my car. Any idea which is correct? (Car is not currently with me so cannot check)
I was wondering if the 15/16 was for big block cars.

Also, I cant find anyone listing the rear swaybar bushings. Be grateful for any heads up on these.

big one for Big Block cars...

slip an open end wrench on the bar or use an adjustable and measure the gap. Hi po small block cars seem to not always have the big bars. Rear bushings would be 7/8", the stem link uses regular height 3/8 center bushings (stock washers are heavier so don't discard), the other end (square end) is the hard one. NOS front C body bushings will fit but they are rubber. Have yet to find a urethane replacement. These are super hard to put in with anything less than a press. They press in pretty easy, just cram them in. The front link to frame rail can use a standard sway bar half moon shaped bushing with a little shaping. You would think somebody would make a kit but they don't.

For the rears, I got a kit from Firm Feel, they are pretty stout, but I had to shim the bushing on the bar to body mount and the bar itself so it would snug to the bar. They are all urethane and come with grease fittings so you can lube them if they squeak.

Thanks for posting, especially the very clear pictures. Was it a straight forward job ie no pressing of bushes required?

I have the Moog part number right here because I am doing mine as we speak .the rear sway is 3/4 using a wrench to get the correct size that is K7061 . Can get off of eBay or your nearest parts store that sells Moog ...I hope this helps you my over seas friend ..take care..
