Re: Floor pan
Also . . . be very careful to not cut the floor support braces unless you plan on replacing them. Fortunately for me, my floor support braces were in good shape but I did have to drill some "landmark" holes from the bottom of the floor near the edges of the braces (drill up into the cabin) so that I could see where to cut floor metal from above.
