This is my first post and im glad to be part of this community. Ive actually done enough research to realize my 81 b210 is really more of a 310 but for the US market. Some of the parts compatibility confuses me due to this reason so its hard to tell exactly what i need to order. I want to put an aftermarket wheel in the car. Ive found that Boss racing makes a hub for the b210 but im not sure if its for the actual 210 or the american b210. Anyone have any info on this or know of a hub that 100 precent fits on a 81?
