32 ford frame width at front axle centerline

I'm building the frame for my '28 coupe. I'm using the front rails for a '32. By all the frame dimension reference I have, the frame is suppose to be 25 3/4" in width, at the centerline for the front axle. 26" for a stock '28, which would place the fenders in the right width at the radiator. However, when I set my rails to this width, and mock in the crossmember and '32 radiator shell, there is almost a 1 inch gap on either side, between the radiator shell, and the inside of the rails. It just looks too wide. Does this sound right? I don't have an assembled car around to check the measurements. What is the width of an installed '32 shell at the rear flange just above the rails?

On installing the front crossmember in a level and square jig, With a straight and level top rail, what would be a close suggestion on the caster angle for the front crossmember relative to the top rail? Going to run a split wishbone with a 4" drop axle. I know the angle is also relative to the ride height angle of the frame from front to back, just looking for something close for a start point.

That sounds pretty close...according to Wescott they build theirs 25 1/4 at the end of the front frame horns..the mounting holes for the radiator are 20" apart..

The castor angle of the front crossmember will be about the same as the castor angle of the axle so the spring acts in a verticle plane and does not bind..What is your proposed castor angle of your axle???

My radiator mounting holes are 20 inches.
If you are using a repro crossmember ... they are short and will not touch the inner wall part of the frame ...



I used a set of original 32 rails for mine ...

my cross member is from Brookville Roadster in Ohio. At the 26" outside width of a '28 frame, it just sets about 1/4 inch inside the frame rail on each side. Says it is suppose to be flush mounted to boxed rails. I think I'm going to extend it so it reaches the outside wall of the rails. It's mostly that the mock up just looks too wide with the grill shell.

I'm going to be running full fenders and a hood with sides, so I'm also going to have to modify the way the fenders and hood shelves mount up, to have it come together right.
