in that case check out bobs carpet and flooring in everett off of... ?evergreen? it's by the value village between there and Everett high school,
they usually have good stuff cheap and can break you off "remnants" or whatever to do the bus in. go with shag man! hahaha j/k
but check them out and 90% of the guys who work in there smoke so they're down to deal and stuff, that meaning you wouldn't go in to the bon and haggle prices with them but they guys are cool like that, i've done carpeting for my parents house throught them over the years so that';s how i know about that. other wise check the usual spots ect ect ect.
do you want me to track down the original color/pattern used in the 1970 Rivera baywindow bus?
or do you just want to make it look cool?
i like the cool factor over the original factor, original is for old people with alot of money, i doubt hippies who rolled these things back in the day cared about originality.... just my 2 cents ! haha, but don't let me sway you! you have to look at it everyday! haha!
