Unbelievable, bracket rivets broke
 

Im in the process of changing the 4.10 rearend in my 3/4 ton to a 3.54 I found in the boneyard yesterday, and I start to remove bracketry, and I notice the right shock mount to the frame has completely seperated, those big rivets have popped the heads off, and the front sway bar has 1 missing as well. I guess I'll just pop them out and replace with some grade 8 nut/bolt

That'll happen if they get rusty enough, or if there's a lot of stress on 'em.

that's why they call them old

I have the correct frame rivets if interested and can make you a tool to install them if you have a torch. Rivets 1.00 each, tool 30.00.

A buck ea on the rivets & 30 on the tool....$36 is cheap on both sides ;) I have 7/16 grade 8 bolts /pinch lock nuts on mine....shocks were moved back to stand em up after the drop. If you run grade 8 bolts, drill so they fit tight in the hole.... crazyL :burnout:

Grade 8s are okay, but overkill by a long shot. Shear strength on the steel rivets is close to a grade 2. I use grade 5 to replace rivets. And, yes, the hole needs to be a tight fit. I also don't mess with lock washers on those locations, red loctite works better.

Agreed, locktite or pinchloc nuts.....lock washers are "tabu" on that stuff ;) crazyL

I use metric bolts to put back in place of rivets I have found some that fit the hole when i put a front swaybar on 3/8 was too small for the hole and 7/16 was too big so i got a metric bolt and nut . I used some of those locking nuts

Thanks guy's, I got some grade 8 serrated flange bolts with 10mm nyloc nuts, fit perfectly and cost me about $3 at the local home depot

I always touch the holes with a 'stepped drill' bit to get the holes round which ends up at 7/16. Grade 8 fine thread with grade 8 flat washers and a pinch nut.
