Where to buy diy lift parts

Am looking to do the DIY lift with the ghetto air shock MOD and I need to know where to get the pieces.also instead of doing the upper rear shock mount drop was going to put four inches of pipe on top since two inches is for stock height thoughts?

there are 4 good steelyards within 20 miles of my house
surely being in pennsylvania you've got at least one

Thanks ended up finding a piece here and there but almost got everything waiting on better square tubing. Also doing the air shock MOD in the process. Found everything at a commercial plumbing store except bolts and square tubing.
