[DeTomaso] 3.2 gears and clutch life?

[adin at frontier.net]

Mathematically, it would be a 2nd gear start to simulate the 3.2 (with  
in about 9% anyway). Check out panteraplace gear spreadsheet.

Not for those who live on steep hills or cruise main, but it will give  
a good gear for the drive from Durango to BFE.
