fabricate

I have a 1950's aluminum boat shell. there is metal seat frames and i was wondering how to get some real seats. any links to videos or sites i can refer to would be great or a brief description. but i guess i need to get some marine grade wood and a certain type of foam and cloth and some how...

i have a 79 ski doo and want to lift the rear suspension to make it look better with spending little money. how can i custom fabricate drop brackets? and what else do i have to do to it i heard u have to drop the front of the track too. how do i do that? do i just make 2 more drop brackets?
