I want to bolt up my high lift to the 1st gen roll bar right into the already threaded hole on the inside of the rollbar. I see Roger Brown has a mounting system he sells but really just need to know the size bolt and thread pattern if anyone knows. I searched but didnt find anything. Also, if you have pics of how you mounted your highlift inside, please post it up. I wont be able to weld anything right away so looking for non weld alternatives.

Cheers!

 

It's the same as the standard seatbelt bolts. IIRC it's like 7/16-20 (obviously not metric). I have also found that hole sometimes needs to be re-tapped from having paint in it.

 

I use the RB hilift mount and it works great!

 

7/16-20 is the correct size

 

COOL! Thanks everyone.
