Im gathering parts for the original numbers matching 340 for my 70 swinger. I have two oil pans, one #294 (orange) and one #394 (grey). Can anyone tell me if either is correct for this application? the grey pan has some stiffening gussets in the corners of the pan rails and holes for the rubber end seals. The orange has no gussets in the pan rails or holes for the end seals.
