Anyone happen to know off hand the size, dimensions, stock # of the bearing for an idler pulley 88'-89'? I know I had a bad (1) somewhere in this house... I just can't seem to lay my hands on it, or recall where I put it, (so I wouldn't forget where it was?). Thanx, appreciate any help, as I have another pulley in need of replacement.

I have an 87 ECU for $50 shipped. PN MD106394.

BOX IS FULL NEED TO SEND INFO ABOUT SHIPPING CONTACTED U SHIPP AND THEY HAVE 5 DAYS TO BID ON WILL SHIP BETWEEN NOW AND 1/1/15 END OF THE YEAR....

(New 75 alt, recent h4 conversion, clean electrical connections)   So I hate when I rev the motor my lights get brighter than at idle. Just wondering if there is any way to improve upon that.   Also, does the battery play a role in this as I'm running a huge oversized 950cca truck battery and a buddy claims that the alternator is too small (75amps) to efficiently charge a battery usually run in dual alt Ford diesels.
