Chopping 49-52 sedan threads. Please post links!

Alright I know there's threads out there showing step by step on chopping these things. But now that I'm actually trying to find them I can't find any good ones that I've looked at in the past. Can you guys post any links that you know about. Thanks!

 

anyone?

 

I'm thinking of removing two doors and doing a slight chop on my cadi in the future.
I have seen some threads on doing the 4d to 2d but not a step by step on a chop.
