Re: smog pump removal.. Belt size?
mine actually takes a little less than 84.5 as well... due to the underdrive pullie that someone put on there years ago.
so go to the auto store, buy belt... try it on in parking lot, if it don't work bring it back in and add/subtract till you get it right, I believe either 84, or 83 worked for me.
