1970 C20 longbed stepside body swap questions.

[MaxxRazz]

I know this has been talked about a lot bit I have some questions that maybe some of you can help me with.

In the process of starting my swap. I have a 70 C20 longbed I plan on swapping the body onto the 02 Silverado 2500 duramax extended cab shortbed.

I know most people I've seen shorten the frame due to wheelbase differences.
Mine is about a 16.5" difference. I dont really have the capabilities to cut and weld the frame besides my harbor freight welder I can barely use.
My main questions is, has anyone gotten around this by either lengthening the bed or making any other adjustments. Just want to know all my options before I start cutting into anything.

Any other recommendations would be greatly appreciated on this build. Thanks
