An Excel file that I built many years ago, just for such things like this:
http://northwest.2bigbroncos.net/technical/shocks_files/shock_specs.xls
After sorting it, the first option that I see:
Maker/Model..............Rugged Trail-Nitro/60K
P/N..........................56031/66031
Ext Length................11.19
Comp. Length............8.07
Body Diameter...........2.00
Top Mount Style........EB1
Bottom Mount Style....EB1
Travel (")..................3.12
"EB1" is an eyelet-bushing mount, I just forget the dimensions.
