Re: Front sway bar diameter
I believe the factory used grade 5 but most folks use grade 8 when replacing. I recommend using Nylocs or loc-tite as they can work loose.
C10 through C30 2wd are all the same shape and interchangeable up to 82 or 89. Personally I wouldn't run anything other than the 1-1/4" bar. But I've been know to drive too fast. Just ask my wife.

Re: Front sway bar diameter
Thanks for info. I have both grade5 and grade 8. I got the 1-1/8 sway bar. I looked at 3 C20s original 2wd, one was a longhorn at C10 parts and. Neither had 1-1/4. So I'll start there not a handling fast truck, but parts chaser. Dips in turns, but not too bad. Not sure if 1-1/4 was a extra HD option?

Re: Front sway bar diameter
My truck had a V6 which is very heavy. No sway bar on it C25. I put in CST 402 from 1970 shortbed truck. It was lighter, moving in right direction there. Amazing how heavy a 305E is.
