Auburn in and ready to go

[MEDIK418]

Well, I just finished instaling a new Auburn Differential in the 89. Took 2 hours start to finish. . .almost. Putting in the oil proved to be the messiest part of the whole thing. Someday, I'm gonna invest in some kind of pump for this type of thing.
Last week my youngest son and I took the cars to Amarillo for some test and tune. Oldest son wanted to know what his would run (he's captive in the Marines) so off we go. Short story. . .one tire burnouts don't make for very good times. Best I could do was 15.8 at 96 after smoking the left tire through first and second. After telling him over the phone, he ordered me to do the Auburn and the Fluidamper he's been planning. I hear and obey. (hey, it's his money)
As soon as the damper is back from the machine shop, (had to match it to the stock one that was balanced) I think lil brother is going to try again. I gotta work this weekend.
Question: does anyone here have any experience with the fluidamper? I'm hoping it works ok.
