Sorry can't help you on the shifter plate but I can give you some advice about your steering wheel. I am 99% sure that the steering wheel that came with your car (is the same that came with my car) and it is not a wood steering wheel (I am pretty sure those did not come until 68 or 69 I believe). What you and I am both should have is a cast plastic (large) steering wheel with a valiant symbol in the center ring with a large chrome 1/2 circle horn ring on the inside. I actually still have the outer portion of my steering will but do not have the chrome horn ring. What you will find is that the stock steering wheel should match the color of the dash and interior. In my case it is gold (and I still have that steering wheel). What I did is I took a grant GT steering wheel and had it painted (by a body shop) to match the color of the dash and clearcoated and it looks totally amazing. What I like is that it has the appearance or illusion of looking stock but it is less dorky than the Giant steering wheel that actually came on the car I also had them put a picture of my dad while he was in the Navy in the center and clearcoat over that as well. I would be happy to send you pictures of my old steering well and the new aftermarket steering will to give you some ideas if you like. I also have located the original brochures for our 65 barracudas and can email you JPEG's of what those brochures look like. I have also found three or four awesome websites for decoding our fender tags and if you would like I can help you decode your fender tag if you have not already done so. I am getting you must have the "formula s"package since you were looking for a four-speed?
