65 GMC rear leaf Flip kit question....

[**grumpy**]

I read alot of posts talking about 67-72 GMC's, but I'd like more info on doing a flip kit on my 65 GMC...

What vendors sell flip kits for the earlier trucks?

And if I leave all the leafs(leaves) in, will I need to notch? I have about 4ft on 5"od 1/4 wall pipe, so maybe I can make homemade notches?

I'm laid-off, so money is tight. I'd like to bring it down out of the clouds soon though.

Thanks all
