The parts list will be invaluable, but the only place that sells the parts at PBR. You can buy the parts individually, but it will cost less to buy the kit. Skateball and Paragon don't share the same parts.
I will be placing another order with them in 3-4 weeks (When the GTB front doors are finished), if that's any help - PM me with what you need.
Nino, the Paragon parts will indeed fit, and in my opinion do a better job 
I hate the Bally linear flipper system, and changed my Centaur to the crank system without any problems, well until I needed the crank parts for a different game so I swapped them out again! You just need to install a full flipper kit from PBR in the existing base plates.

are he linear flippers installed on electra? Some strange setup happening on there
