all the coils I've seen on Monteros seem to be interchangable. Diameters are the same. wirediameters vary but they will fit.
I have Old Man Emu 910s on my SWB. They are really made for LWB Gen 2s and M. Sports. They give me lift and good windy Mtn. road handling.
The down side is possible pinion angle change causing vibration.
Hope this helps.
