extending cab

I'm thinking of extending my cab on my 37, 4" so I can have more leg room. As I've never done this before and have read some on it, I would like some advice from you who have done this before. What is actually involved?

my wife found a site (i wish i would have saved it) maybe she still has it , but the guy used another cab to cut the sections needed to extend it . i will be watchin this thread as now you got me couriuos myself ..

i would so the stretch in the doors. will still look stock but have the extra leg room..

I've done it a few times, some pics in my gallery of a chebbie pickup we stretched 7". Easiest way is to find a spare set of doors. Use the front of the doors you have, cut them in a place where all the lines are straight, then cut the back portion of the donor doors at the point where the length matches the extension you want. Butt the two doors together. A flanged joint on the door will strengthen the skin considerably and making the welding a lot easier. Once you get the doors back on the hinges, cut the cab and fit the door jamb to the door. Before you cut the cab, make sure it is very well braced on the inside. Things move around a lot when you start cutting.....

I did a 3" stretch. I removed the doors,cut the cab & pulled it back 3" on steel rails tacked to the frame. Once the sheet metal work was done on the cab, I cut the doors above the belt line & welded the rear of a second set of doors on. This reduces metal work & warping.

Here are some more pics....

Neat project, good luck...
I seen a 1957 ranchero that was made into a extended cab, looked good.

Don, Great job. Hope mine comes out as good. Dave thanks for the info.

My pleasure, Let me know If I can help. This is the 5th trk I've done.

You're welcome. Don and I did the same thing at the same time using the same procedure!!!! Thought it was really weird when it happened!!! Anyway, it works great an really changes the style of an old truck plus making lots of extra room in the cab!!!!

Hey Don Meyer, I love your truck (body). My oldest Grandson and I are working on a '47 ford pickup, but don't have a body (bed). I have been watching, searching the internet car sites for ideas. I have like some where the owner cut off a car rear and adapted it as a p/u body, make a bed inside. Seen one done with the rear of a Caddy Eldorado. I really like those fins. What year was the body you started with? oldrodder43 Perley

It was a 94 Chevy PU bed narrowed 13" w/repo narrowed fenders welded on to the bed . The bed sides were smooted & Caddy fins welded on(26' of welding).
This is a trk I worked on for 3 yrs & to date is unfinished due to health problems.
