I got this crowfoot extension for my torque wrench so I can torque my heads, I'd use it on the cylinder base but not enough room. Could grind it like my 9/16th chevy door spanner but I think I can get along just fine with the spanner for the cylinder base. You need to adjust your wrench to the following calc I found here:
http://www.norbar. com/calculators/torque-wrench-extension-calculator.aspx

M1 = M2 x L1 / L2
M1 is the torque setting of the wrench.
M2 is the actual torque applied to the nut
L1 is the normal length of the wrench
L2 is the extended length of the wrench
