Dear Welder Series…
Do you have a frame C notch kit for the rear suspension of a 38 Chevy?

Dear Fred…
Thanks for asking, Fred.  If you want to put a simple c-notch in the bottom of the frame rail for rear end clearance, we have #12203.

We also have the frame curve sections, as shown here .

I hope one of these will solve your problem.
