I just received a SE ignition & coil kit labelled as kit no. 31775-01A. This kit is listed (in the HD instructions from HH website) as containing ign unit no 31778-01A & coil no. 31704-99. Turns out that when I open the box the ign & coil are different numbers - those listed in kit no.31721-01. This kit I have is listed for 99-01 FLHT/FLT & mine is an 03 carbed FXST, 1550 & 9.4:1 comp. The instuctions for the actual units that I have says not to be used on any other model, but also says they can be used with heads milled up to 0.050'' and high performance cams? Could I do any damage if I fit this kit? Cheers ..
