PG260D and PG260Dpin
PG260 D starters have external bolts holding them together. The back plate is practically flat. The magnet housing portion (not including the back plate or the nose cone) is 79mm long as shown. “Pin” refers to the solenoid small wire plug in, as shown in the last set of pics. The solenoid is the only difference between the PG260D and the PG260Dpin.
PG260F1
The PG260F1 has external bolts holding it together. The back plate has a protrusion giving it the nickname “bubble back”. the magnet housing (not including the back plate or the nose cone measures 97 mm long as shown.
PG260F2
The long bolts that hold the PG260F2 together are internal. The back plate has a cupped shape to it. The magnet housing is 80mm long (not including the back plate or the nose cone.)
PG260G and PG260GPin
The PG260G has external bolts holding it together. The back plate is almost flat except for a very slight protruded circle in the middle. The magnet housing is 89 mm long (not including the back plate or the nose cone.) “Pin” refers to the solenoid small wire plug in, as shown in the last set of pics. The solenoid is the only difference between the PG260G and the PG260Gpin.
PG260H and PG260HPin
PG260H starters are similar to PG260G when viewing the back plate and the 89 mm magnet housing. However, the PG260H has internal long bolts holding it together. “Pin” refers to the solenoid small wire plug in, as shown in the last set of pics. The solenoid is the only difference between the PG260H and the PG260Hpin.
PG260L
The PH260L series starter has internal bolts holding it together. The back plate has a raised up portion in the center. The magnet housing is 99 mm long (not including the back plate or the nose cone.)
PG260M
Most widely found on Chevy and GM truck or SUV. Also on some Cadillac. Easily recognized by the two 44mm sections from the side view : The magnet housing and the backplate.
Different types of solenoids
All the PG260 series starters all have the same solenoid except the “Pin” types. The pic on the right shows a pin solenoid. Notice the round terminal where the small ignition wire hooks up.
