Bolt in frame connectors

[Silver R/T]

I was browsing ebay for Charger parts and came across these, seems like good deal. No need for welding and they're powdercoated

I'd still weld them in anyway.

I don't see the point of mounting them unless they're welded.  Bill440RT mentioned an epoxy or something that could be applied which becomes stronger than typical welds; maybe you could try that instead of welding...

The whole reason for installing frame connectors Is to stiffen frame. Weld em anyway.

[tan top]

 yep , weld them in  , waste of time & money other wise ,    

lot of fancy connectors about now for sale , just get two sutable lengths of 2"x2"x1/4" box  , weld them  

[bill440rt]

If the opportunity is there, then YES definitely weld them in. 
I bolted them in combined with panel adhesive as they were installed as an afterthought on a fully painted underside. I used adhesive to provide some added strength over just bolting them in alone. There's NO WAY I would just use an adhesive in this application. Welding would be best.

I'm with everyone else on this one, mine are welded in

I agree welding is best, but even bolt in connectors are better than nothing. Without sub-frame connectors that area of the car can easily deflect .38 to .5 inches on a torsional load. With bolts through a hole, how far can it move before the shoulder interferes, maybe .03. That's a big improvement.

I don't see point of welding them in since all they're supposed to do is connect front and back frame, prevent twisting

If you don't see the point of welding them, re-read Cooters comment.

How would you feel about your Charger bolted together instead of spot welded?
Now, instead of weighing 4000lbs, it seighs 5500 lbs with all those bolts and rattles horridly.

Actually, they aren't designed to resist twisting. They originated on the drag strip to resist beaming which is the bending of the car in the middle. The additional torsion resistance is just a side benefit.

I'd like a better view of those connectors, I'm trying to sort out how they attach from the pics. 

[HPP]

I suspect those may be a case of "part pictured is only representative of the part your buying and may not be the actual piece."

I'll try a search to the maker....

Pick up a set from US Car tool they are nice they are what I have on mine.  http://store.uscartool.com/66-70-B-Body-frame-connectors.html

[Ghoste]

Those are the ones I think I want to get.

[don duick]

bolt them first then jack the car try to open and close the door. this should give you some indication. if no difference then weld them

http://www.competitionengineering.com/catalog/images/C3117_inst.pdf   Here is a PDF of install instructions. 

[Ghoste]

As a part that is sold as "bolt in" they would natrually instruct on how to bolt them in.  I would still wanted a set that were welded.
It does include a good diagram of how.

Yea it says "Weld in for race." in the PDF. I like the extra rear tie in detail also, seems stronger. I want to add some bolt in's sooner or later but only to sure up and old chassis, not for "Race". I want mine removable. 

[Ghoste]

I didn't even notice that part, I can understand wanting to be able to remove them.

How thick is the metal in the US Cartool connectors?  Anybody know?  

[tsmithae]

12 ga, I am about to instal mine, once my floor goes in.

If you're worried about bolts loosening up, use some lock-tite on treads.
