Thanks guys!
Len - Are you going to run fenders on your sedan? I don't have the sedan kit yet, but on the coupes you just need to trim down the interior rear bulkhead, interior side panels, and firewall the same amount and drop the body right over the frame rails. Then just either section the grille shell a like amount and keep its mounting points, or trim up the mounting points and drop it down thru the front frame horns.
If you want fenders, you'll have to remove the rear fenders from each running board/fender assembly and trim off your channeled amount from the front bottom edge and then reattach.
That was all for a channeled body. If you want to section it also, like mine, I take the easy way out and trim up from the bottom the amount I want removed.
Here's a picture of my current '32 next to a box stock body:
HTH! Channeling and sectioning present many challenges because everything above the frame rails is effected - interior pcs, steering column, engine clearance at firewall, etc. PM me with any more questions, if ya want.
