I was referring earlier to the "Nodular Iron" center section on your web site Cass. The one with the big "Y" casted on it. Same one Yukon shows.... https://www.yukongear.com/productdetails.aspx?ProdID=5164

I thought that was one of the same.... my bad, I see now that there was mention of heavier caps etc...

RMCHRGR.... MP discontinued those aluminum centers back in the late 90's. I got them at dealer cost of $400. Never used them and sold them.

personally I would have upgraded a long time ago, but I then realize that the car in question "might" see the track once a year. That alone will put the odds in his favor.
