Dear Welder Series… 1974 Triumph Spitfire Mustang II?

Dear Welder Series…
I have a 1974 triumph spitfire with a sbc, it has a frame width of 19″ and a  track width of 59.5″, i would like to install your mustang 2 crossmember do you see any reason why your 56″ would not work if I narrow it? Thanks for your help, also could you send me your catalog.

Dear Randy…
Randy, I’d like to check a couple of things…
We measure track with as the distance from one wheel mounting face to the other side wheel mounting face. 59-1/2″ sounds like too much for a Spitfire. Please check this.
The frame width, outside to outside, must be at least 26″ to mount the upper towers.

I’m confident that you will be able to put our crossmember in your frame, but it will require some frame mods to do it.

Thanks for looking at Welder Series parts.

Dear Welder Series…
Paul I rechecked the track it’s 49.5 in what kind of frame mods would have to be done?

Dear Randy…
Sounds like the frame width is going to be ok, Randy. Minimum width for a 56″ kit (actually 56-1/2″) is 26″. You want 7″ less (49-1/2), so the minimum frame width would be 19″. There will be other “ambushes” along the way, but see how Grant Schwartz did the Volvo at for some ideas.

We will get a catalog in the mail.

Thanks for looking at our parts.

Paul Horton
