The old saying "you get what you pay for" really rings true. I purchased an "economy" Mustang II crossmember from Speedway Motors for a '49 Chevy PU. After unpacking it I noticed that there was no notch cut in the upright portion of the crossmember to fit it between the frame rails. Does anyone out there know how much I should "notch" the uprigt. The instructions that come with the crossmember do not say anything about notching it. The distance from the top of the upright to the top of the actual crossmember is about 3 3/8 in.

I just measured the Heidts unit I installed in my '53. You need to mount the crossmember so the center of the lower "A" arm front bolt hole is 2 5/8" below the bottom of the frame.

Thanks for your help. I was afraid if I cut it too deep or too shallow I would have steering geometry problems. I really appreciate you taking the time to measure your '53. You have saved me from a very large headache.

I just installed a tci in my 53, if you are talking about where the frame y,s out just cut it all out.

The part in question is the upright part of the crossmember. The portion that fits up between the frame rails. I notched the uprights so the center of the bolt hole of the lower control arm is 2 5/8 inches below the frame as Centerline suggested. That seemed to put the upper and lower arms where they should be. Everything is moving along now and I hope to have my front and rear suspension completed soon.
