Joe,

Forgot to add this.........It depends on the year model 13B also........The 86 to 88.5

2nd gen had heavier rotors and what I reported is true.........The 88.5 to 91 2nd gen

13B have rotors the same weight as the 3rd gen and should be able to use the 3rd

gen rear counterweight.........You have to be careful with the 88.5 to 89 2nd gen to

make sure you have the lighter rotors (they are 9.7 to1 and have a machined rather

than a cast depressions in the rotor face)..........Sorry for the omission..........

Joe,

A 3rd gen counterweight and flex plate will fit 2nd gen 13B but the counterweight

will put the 2nd gen out of balance unless rotors and both counterweights from the

3rd gen are installed also...........On another note if this engine is for an A/C using

Tracy's redrive you must use a 2nd gen flexplate........FWIW
