Weld in roll bar to firewall supports

[ProPont]

I am trying to find out who makes the welded in round roll bar supports that are welded into the firewall so you can unbolt the subframe. I have seen these used by a few shops. I hope I explained myself correctly.

I'm interested in a set too.

Make them. How do you want the tube to attach, like a swing out door bar, or just through bolted? A local machine shop should be able to turn you a simple part for the through bolt design. Don't know of any off the shelf items, other than the door bar adaptors from various vendors. If you can't get them done locally, let me know, I'll try to fix you up.

Hotchkis makes a bolt in unit.

Check with Brett @ fab53 he maybe able to make you a set.

^^^^yes, those^^^^

They are very simple to make if you have a lathe, I just happen to not have one.

I can check with Matt to see if he still has the pattern in his CNC that we used for the OLC...

Flat plate - two hole saws and a drill bit... cut the big round first - cut the inner - mark a pattern for the bolts - drill and finish...

:D

I like to cut the little hole first, then weld the slug back in so that I can pilot the bit for the larger hole saw. Then carefully body saw the tack welds on the plug to remove. After that lay out the bolt pattern and try to hold the disk with your hand while drilling the holes with a uni-bit and air drill. After bandaging your hand and fixing the dent in your new fender after the drill threw the disk across your 3 car garage at 100mph debur and viola! Done!

ALL WORTH WHILE PROJECTS INCLUDE CUTTING, WELDING, BLOOD and CUSSING! :lol:

Seriously, not everything has to come out of a CNC machining center. Greg hit the nail on the head! Sometimes keeping it simple is the best solution! :thumbsup:

^^^^^^^^^ That is hysterical!



Can't tell you how many guys stop by to do a "little project" --- I pile some tools on the work table and tell them "have at it".

Amazing how many can't think thru the steps and cut the big pattern first then can't figure out how to cut the smaller hole now that they don't have a pilot hole.... SO then I have to rescue the thing by setting up the mill/drill and punching the small hole in for them. Takes longer to set up the machine than it did to do the work...


Most can't lay out a simple pattern --- or know enough to make the attachment piece and the plate and drill them together so the holes line up etc... let alone = clamp the piece and use a transfer punch...

I get some good laughs out of all this... and it's not because I'm a smart ass... I've made all the same mistakes!

My biggest helper in "the shed" --- I'm too stupid to think complicated.

You don't think I'm creative enough to make that stuff up do you? :lol:

SpeedTech also sells something similar.

[Vince@Meanstreets]

let me know, I have them for 1 1/2" and 1 5/8" tube. Two piece with hardware is $46 shipped.

Did you see this set up, a bit different, but does the same thing, called a Gemini connector. I spoke to Mike at Chassisworks when I bought my G-link rear end set up and they sell just the lower machined part. Requires welding the base to the frame.

I clipped these photos from the installation instructions.
