Is your extended cab the "old" body style (GMT400 - '88-'98)?  I ask because as 1 tons and 3/4 tons they were available as "classic" for '99 and '00.  If it is, the length difference between a regular cab and extended cab is almost exactly 24", give or take .5".

With this in mind, look at the two shorter wheelbase versions of the 3500HD.  135.5" and 159.5" - 24" difference.

There have been quite a few homemade extended cab 3500HD's built using the 159.5" wheelbase frame, extended cab body, and a bed normally meant for a 60" cab-to-axle, or in other words, the 135.5" wheelbase frame.

Hope that makes sense.

If your extended cab is the newer style, not sure how much the measurements differ.

I do have the newer body style,I've read where people notch the back of the cab for frame clearance,there about a 8 inch difference between the 98 and 00,the 00 being longer.If I went with a 4 door chassis,there should be plenty of room,its 32 inches from the center to rear cab mount.

I have seen modifications where an "extended cab" was cut/notched in the rear to channel around the frame rail as you mentioned. As far a finding a 4dr 3500HD chassis...that could be a challenge since GM didn't make them, they are aftermarket conversions...but they are out there.
