Project Midnight Swinger

That is a bend over and take it price, local shop here is $100, and he gave me a gallon of gear lube.

I have yet to put the 4.30 gears in my Duster to replace the 3.23.
He also told me the best way to break in gears, is to run it easy down the road for at least 15 minutes to warm the rear end up.
Park it over night repeat 2 more times. Basically heat cycle the gears to set the wear pattern.
I think that price is only marginally higher than I paid to have my 489 case set up with my spool and new gears last summer. This is in the Detroit area.

And then there's that break-in thing. I wasn't putting the street tires and mufflers on the car and driving it on the streets at that time. So the break-in was a warmup down the return road prior to the track going live, then a burnout, then an 11-sec something pass!!
