ATR Sway Bar question

[nickygn23]

Gentlemen. Quick question. What size Grade 8 hardware did the ATR rear sway bar come with? Got my hands on on a second hand one. No hardware included. Thought I had the hardware but..... You know how it goes. The one pictured is not mine. Mine still needs to be sanded and painted.

not from my experience but from others, one must use locktite or some type of non loosening type fasteners or they come loose over time. I guess the twist on the unit puts stress one the fastener and results in the loosening over time.

But do you know what size they are?

The original ATR bolts were 3/8 x 3” long stainless bolts. I managed to break 2 of them after a couple of years. I replaced all of them with 3/8” x 3.5 long grade 8 bolts . I have Hotchkis rear control arms and the longer bolts give more thread engagement. Use locktite on the threads or a quality locking nut.

I used 7/16 and had to open up the holes just a bit.
