Ok I got a half shaft from a local junkyard which came from a 94+ Integra(manual transmission). I tried to fit it on the b20 block but it just doesnt want to fit up. Im not to sure if my b20 is auto or manual. Should it matter if it is or not? I need to know why it doesnt fit. Do I need a half shaft from a auto Integra? Any help would be nice and greatly appreciated. Thnx in advance.
