I just got a 1991 civic ex for $200 everything is in great workin order but it cant be registered. Im gonna swap evrything into my 91 crx dx is there anything small that might be overlooked when doin this swap I know its relatively basic but I dont wnna miss anything stupid. the crx is a d15b2 duel point with an auto. and the ex is a d16a6 with a 5 speed. thanks
