Sway bar sizes.
I'm wanting to replace the front and rear sway bar bushings on my 88 formula 350 and not sure what size to get, if anyone could point me in the right direction that would be great.

Re: Sway bar sizes.
If you have a digital caliper check the swaybar at the thickest portion. Or, use a metric wrench and see which one fits over the swaybar. Or, check tour RPO code against the link below.

Re: Sway bar sizes.
Best way to find out what you have is to measure your bars. If you do not have a dial caliper you can use metric open end wrenches to find the size... Keep trying diff. sizes untill you get a good tight fit around the sway bar... That size wrench will be the dia. of your bar.
Or you can even use an adjustable wrench or vise grips and a ruler/tape measure, put it on the bar and tighten it down, remove with out changing the adjustment, then measure the inside of jaws... That is your bar size
