Well after waiting for about half a year now to get all the parts together, today was finally the day I got my gears and trac loc installed. What a difference! I haven't gone WOT yet but 4.30's are perfect for the Mark VIII. I'm still using my stock driveshaft and I don't get vibration until 85-90mph which doesn't bother me. With my cutouts open I had vibration before the gears anyway. Now once I get the gears fully broken in, i'm off to the track...
