The 5/16" square hole in 76-77 radius arms

[Crawdad]

Guys I need advice on this matter. I have a set of good 73 radius arms. At the moment I am lacking 76-77 radius arms for my 77 build. The only thing missing from the 73 arms is the small 5/16" square hole. I need that hole for my anti-sway bar that I kept from my old 76.

My question to the gurus is.... Would you drill a hole in the 73 arms and call it a day? I'd obviously need a pattern to go by. My only option is to buy a 76-77 arms. I have an opportunity to buy a set for $60 but I have to drive down to Macon GA to swap out.

Thx, Matt

I'd just drill em'

Get a good measurement as to where they are supposed to be and go to town.

That's my thinking as well, it's just cast steel arms missing a square hole. I figure I could make a template off my 73 arms. Then lay it over a 76-77 arm and just mark the square holes on my template. Heck, instead of making a square hole, why not just drill a hole and tap it.

Square holes are easy to make with a drill bit and the right size flat files. Go for it!
