1988 External clutch conversion w/ 99 Wrangler ax15. flywheel question.

[dkroll]

I have swapped out my bell housing for a "later model" external clutch set up, I have two flywheels sitting here with many questions;

 

1). The bell housing was from a 99 wrangler, I believe.

2). I have an old flywheel and pressure plate from "somewhere", not sure it was for a different type of tranny or what.????

3). I have the flywheel which was from the '99 (I believe, but not 100% sure).

 

Both flywheels look identical for the starter teeth (gears), but both flywheels have totally different "teeth" for what I believe are for the crankshaft position sensor. 

A).   One (the newer one), seems solid with 3 sections with indent "teeth" with 4 grooves in it.

B). The other has many teeth in groups of three with 20 teeth and a gap between (if that makes sense). (old one).

 

Question one;

 With this truck being an '88, I feel that the crankshaft position "teeth" need to be compatible with it, so I ask;...

Is "B" the right flywheel to use?  I that configuration correct?

I wonder how the system worked back then and if B). will work nice with the pressure plate and everything (clearance-wise and all ).?

 

Question two;

 Are there any good videos or sites out there for this particular situation? I know this has been done many times, but I either need some reference or chat with someone who has done this.

 

Question three;

 When did they change this flywheel configuration and why/what is the difference?

 

I just don't want to put this together wrong and find out I must re-do a mistake.

HELP!!!
