Well, it is finally IN!!!Only took a few hours to strip the old 18 spline out and clean up a little, (laying under the car gets harder every year, and with temps in the 20's and 30's in an unheated garage, I feel OLD!) Finished getting the 855 bolted in about 7 PM on a sunday. Again, the machining on this unit is better than just about anything I have ever bought.It truly 'slid right in' and everything lines up as stock.Filled up 3 quarts 75/140 synthetic for break in, not a drip, not even any weeping anywhere,let's hear it for O Rings! Finished up a few small details last night, and if the weather ever warms up and dries out, I'll be ready.
