accord cylinders?

im wanting to know where a good place is to get cylinders for the rear of my accord (its a 1990)..also the mounts if anyone sells them, prolly b easy to make though..a guy out here wants 390 canadian for each cylinder, sounds pricy to me..any help is great..

i don't know if there's a difference between 90 & 94, but there's a guy at the bottom of the page (classifieds) that's selling all 4 for 250. i know nothing about cars, but someone else might.
