Dear Welder Series… track width

Dear Welder Series…
I have a pro street car and was wondering the best way to measure it out to get the right track width for my front end.

Dear Nick…
Nick, mock up the sheet metal and position the front wheels & tires where you want them.  Note the distance between the wheel mounting surfaces.  This is the “track width”.  Our kit track widths are nominal dimensions because the actual dimension depends on the brakes used.

If your frame is already fabricated, tell me the inside and outside frame rail dimensions.  It will help to know the frame height (top & bottom) at the spindle and the spindle height.

Give me those dimensions and I’ll reply right away with the kit I think you should get.

Thanks for looking at Welder Series parts.

What do you mean, “modify the rails”?

We have had quite a few questions about installing our Mustang II kit in cars that don’t lend themselves well to a conversion. Sometimes “modifying the frame rails” is necessary. What exactly do we mean by that?

I thought I’d put together some pictures that show a few frames that have been modified to accept a Mustang II crossmember. If you have any questions about your frame or any of our parts, please email or call toll-free: 1-888-648-2150.
