Suspension

Question

I am preparing my 79 YZ250 for vintage racing and need the technical info on the rear suspension and monoshock. I am trying to locate a FOX monoshock and don't want to get the wrong one so I need the dimensions. If you could email me the section containing the suspension info, it would be greatly appreciated.
Checking in our 79 FOX catalog we found out that FOX made a version of the Monoshock for the 77/78 YZ and the 79 YZ. FOX also made an 11 inch and 12 inch travel version of each shock. The 12 inch versions fit a stock bike but made it turn quicker since the rear of the bike was slightly higher. For reference the following were the FOX part numbers for each version. The part number may be stamped into the body of the shock.

1977/78 YZ125/250/400 11" Travel Part # 99-1000
1977/78 YZ125/250/400 12" Travel Part # 99-1001
1979 YZ125/250/400 11" Travel Part # 99-1002
1979 YZ125/250/400 12" Travel Part # 99-1003
