First off I wanted to thank everyone for their help and suggestions.
So far this is what I found lying around the house. As you can see I have a couple different exhaust pipes, paper clip, q-tip post (blue), WD40 straw (red), and a 3M Dust Remover can straw (white).
The ideal thickness would be the 2nd set of exhaust from the top but its the ones I need to use for the Merc, go figure. Next best option would be the 3M straw. Still not sure what I'm gonna use.
I also have a 32 ford kit that has a couple sets of stabilizer/radius bars, is it possible I could use a set of them?
Amongst that problem my other issue is still trying to figure out how I'm going to fit everything (4 link, shocks, exhaust, and brackets) at the rear with the over sized airbags.
As you can see here I did a quick layout where I think the 4 link and shocks will work but its so tight I have no idea how I'm going to squeeze the exhaust by to reach the desired exhaust openings.
Is it realistic to run the pipes over the gas tank and spare tire?
Sorry for all the questions but this is the first time attempting any of this so any sort of help/suggestions/opinions/photos are much appreciated.
