woohoo....speedometer is accurate now.....peak of the little bounce is your speed if it is lol. Had to bump down from either a dark grey/light blue (looks light grey to me) and a blue drive......to red (37 tooth). I'll have to look up speedometer bounce now lol. I had to change the gear housing to go from 44/45 to 37. $40 on fleabay shipped. Got it from American Hotrod Solutions. No more adding 10% on the fly. Was kinda cool seeing the speedo hit 80.
