Help me find aluminum for my trailer

[SuperDutyScaler]

im kinda picky about stuff so i used a old saw blade i had that was getting too dull for wood. it actually cut through the stock trailer parts like butter! plus all the cuts were perfectely square to each other that really helped with joining the sides together. I have to add the grey wood risers still and i have to cut the wood to length so i can finish the deck. im going to take the chrome rims and try to make a set of Budd's out of them with a circle cut of styren. Im going to paint the entire trailer black, also the trailer ended up with exectly 41".
