If you put 2 peices of 2x2 1/4" like you have and took 1 peice of 2x3 3/16 like they suggest and put them in a press to see what would bend first. The 2x2 would be stronger.
well i personally think that a single rail of 2x2 on a mini such as a mazduh or nissan would be sufficient enough to hold the weight of ur truck and any other mini. as long as u make the transition flow well, not just a straight drop it will be just fine. my 93 mazduh has a single rail of 2x2 down each side and it is very srtong no twisting or bowing, also my truck is back halfed with 2x2 as well so what u have is very strong and very safe so go ahead and plate the inside and call it done ...
so know i am getting bashed on rps b/c this frame is apparenty going to break and the truck is going to crash into a playground. Kill 110 kids then crash into a daycare and blow 35 babies into pile of tastey salsa. I will grab the tortia chips.
yeah i know that part is week, i havent got that far yet, look at the first pics in the thread, that peice wasnt welded in yet, and then im gonna box it in probably... sound aright?
