Well, just as I suspected 18300-N4200 is no longer available from Nissan. Thanks for the website Sarah, I'll check it out. In the meantime if anyone has one of these in good shape, I would be interested.

I ordered some bronze bushings today. The inner diameter is pretty close at 0.315" (spindle is 0.31") but the outer is 0.44" instead of 0.395". My plan is to chuck them in a drill press and file/sand down with emory cloth to get them to the correct o.d. Cost of the parts is about $9.00 and I'm guessing is will require 45 minutes of sanding & polishing.

post some pic's when you are done so we can see how it works out..

Yeah, I just got a Black Dragon catalog in the mail and found the part this morning. Pretty impressive that they carry such an obscure part,and definitely an easier way to go, but I'm still going to give the bronze ones a shot.

www.mcmaster.com should have a ton of stuff like this. They are great for odds n' ends

Well I did get this done. I'll have to go back and take a pic. It came out great-I left the bushings about 5 thousandths large and press fit them into the bracket with a C clamp and then "line honed" them with a 5/16" drill bit. It is extremely smooth, with zero play.

I also modified the bar that turns the linkage on the balance tube. I welded a bead onto the round barstock, and then ground it square. It now fits snugly, with a larger contact surface, but still slides to allow for engine movement (quite ugly I might add since I'm not that great of a welder). I think that eliminating the play at these 2 points will make a huge difference in the feel of the throttle. I'm anxious to get the car out once I've completed the suspension bushing replacement.

Thanks, again for the input here.
