The original complete linear flipper assemblies are these part numbers:

ASE-1587-112 Flipper Assembly Complete, Left (specify coil number)

ASE-1587-111 Flipper Assembly Complete, Right (specify coil number)

Correct original flipper bat/shaft is:

ASE-2214-24 Flipper Bat with shaft assembly, White

Individual parts making up ASE-2214-24:

C-611-5 White Flipper Bat only (use a # 6 by 1/2" long truss head screw to attach)

A-2747-11 Flipper Shoe and Shaft

Individual parts that make up a linear flipper unit:

P-6264-134 Base Plate (used for either left or right, it has holes drilled for either side). Earlier base plate A-613-41 (specify Left or Right) can be used.

A-613-127 Coil Stop

P-108-53 Front coil bracket

S-496-217 Plunger, Linear Flipper

P-6665-637 Stop L Bracket, Right (Marco stocks this)

P-6665-636 Stop L Bracket, Left (Marco stocks this)

C-537-8 Snap-in Nyliner

C-649-53 Nylon Flipper Bushing

A-3711-5 Flipper Pawl, Right

A-3711-4 Flipper Pawl, Left

SP-100-363 Flipper Return Spring

ASE-982-1286 EOS Switch Bracket & Switch Assembly, Right

ASE-982-1285 EOS Switch Bracket & Switch Assembly, Left

Note: the coil stop, EOS bracket, front coil bracket, and nylon bushing can all be attached to the base plate with 8-32 x 3/8" long screws. Some original base plates had the coil stop holes threaded for 10-32 x 3/8" long screws, but other holes were 8-32. The EOS switch is attached to the switch bracket with 5-40 screws of the appropriate length (usually 5/8" long or 3/4" long)

The earlier mech is superior to the linear assembly IMO. There have been troubles with obtaining all of the parts needed to build a complete linear assembly anyway. Over the past several years, people have reported "sticking" linear flipper assemblies due to magnetized plungers and/or coil stops. The linears are a pain in the ass.
