Title: Subframe connectors
Post by: Bolted to Floor on December 01, 2013, 09:51:52 PM
Hi Guys, I need a set of subframe connectors for my 67 Mustang. I understand that weld-ins would be a better way to go. The car is more for cruising than drag racing, just looking for a way to reduce the flexing. I have added the passenger side torque box. Anyone got a recommendation?
Thanks, John

I know guys that have used these, they are really nice and a clean installation. They are weld in though. If you read the description Global West doesn't believe bolt in connectors will function on a Mustang. They are available from Summit and Jegs also.

Its 20 years since i had a Mustang but if my memory
is right the reinforcements  from the convertibel was
reproduced.
Inner rockers,torqe boxes,behind rearseat from wheeltub
to wheeltub, if you want a "stock"look

(just a pointles reflection but)
I have worked on a lot of Mustangs for customers
and it apears like the Mustangs sold new in Sweden
all had the torque boxes and the "export"brace even the six cylinder ones
when the ones imported later had sometimes non tq box
sometimes on drivers side and conv. had on both sides

Competiton's 2x2 square tube sub-frame connectors are heavy, weld-in pieces that I put on my "70 Mach 1 long ago....and would still use again today. No other firm I've found even today offers nearly as heavy-duty a connector. See Jeg's, Summit, et al for a purchase.

I purchased these a couple of years ago, they were much less expensive then. I have not installed them but I like the concept they are welded in 2 locations on each end.:

These are some of the cleanest that I have seen installed. They do need welding, but don't hang to low and don't go through the floor pan. They almost look like a factory installed part.  http://www.spintechmufflers.com/mustang-subframe-connectors/-39-65-39-70-mustang-sub-frame-connectors/prod_65.html

I have used the Global West on a few mustangs including my 67 mustang. I feel they work great.

I added a vertical tube in between the subframe connector and the car's rear subframe just below the front leaf spring mount where the bolt goes through that was added later and not in these pictures. (In the first picture it would be where the emergency cable is hanging down.








Title: I used a high grade commercial epoxy to bond my Global West Subframe Connectors
Post by: Qikbbstang on December 02, 2013, 05:06:28 PM
The epoxy is rated at over 3500#s per sq in. I mega cleaned up the bonding surfaces (including removing the Global Wests powder coating. . For my own test I bonded two 3/8th's x 2" x 4" welding test bars and tested the result with a sledge and monster vice. I bent the steel into a horseshoe w/o any failure of the bond.
           If your near Florida (shipping is absurd $) I'll cut you a deal on a virgin in the box set of Global West Bars for 67-70 Mustang.

do it , it makes a big difference - i put the weld in ones on my 69 mach . I had a crack on my driver s side shock tower so drilled a little hole at the and bottom of the crack , welded it then made sure my car was level on jack stands on the garage floor and welded the connectors in . Then take it one more step and get the one piece export brace , it all makes a big change in the car .  I also did the shelby under rider traction bars with the 5 leaf mid eye leaf springs , 67-70 stangs are same ..

Thanks for all the replies. I have thought about trying to fab something like the Spintechs for a long time, glad to see someone actually makes it already. I like the look of the global west also. I will do some more digging around before I make a final decision.

bn69stang If the one piece export bar ties the shock towers back to the fire wall in a boomer rang shape, then it's already on the car. One less thing to buy.    8)

There was an article on the "best fitting" sub-frame connectors for a 67-70 Mustang a long time ago. I can't remember now, who made them. They were a bolt on connector, that was welded anyway once installed. I welded a set on my brothers 69 Mach1 about 10 years ago. I did add a few more pieces of metal here and there, on the ends to beef it up a little. But basically, it had nice fitting and strong ends, that fit good, laid up against the floor-pan but didn't need cutting or go through anywhere, etc. It was 2x2" square tubing with 1/8 metal flanges that went around the front frame, and on the back, tied into the torque box and front leaf-spring mount... lined up with the bolt for the front spring, etc.

I want to say it was Competition Engineering, but I am just guessing. Maybe do a Google search... It is advertized as a bolt in, and could be done that way, but for the best strength, (the main reason for installing them) weld them in. Your rear quarter panels will thank you, if you do any hard launches with slicks...

You should look at Total Control Products sub frame kit it has an x brace along with a drive shaft loop , it connects front to rear with an x in the middle ..  I M O  that would be the way to go .. Bud

My bad on missing your comment bolted to the floor , yes you have it then and they make a difference verses the 2 single piece set up .. Thats what was on my car , and by the way Carroll Shelby used the total control products on his continuation gt 350 s and 500 s in recent years .. Bud
