The problem with Prestolite is the wires are little "Solid" copper wires going into the distributor--No matter how well you tie 'em up and support them they vibrate and break---Living example now typing to you!...........MOTORCRAFT USES STRANDED WIRE, I THINK IT IS 18 GAUGE.
The other problem it has is the darn "Bellows" contained in the white plastic (this is how the advance operates) will also split/ break/ get a hole in it--PRESTO!!! No timing advance and vacuum leak all in one shot!!!---You won't know it until, you experiment with your timing gun, and see it does not advance!
Darn modules seem to die more often too!
The problem with the "One Wire" distributors is it will not work with the "Resistance Wire" (normally feeding the coil) from the ignition switch--Full 12 Volts must feed the NEW STUFF, and you must tie in a regular wire in behind the "SPLICE" where the Resistance Wire, comes into being (basically replace or make a "Twin", for the "RW" out of regular ole wire to be the new "KEY FEED"
You are really not gonna gain much, just because you are wanting to use the "IN THING"...A "High Speed, Low Drag" Aftermarket coil on the Motorcraft system, will be super, and you will see no giant leaps in Performance, which ever way you go!
This is what I found, nothing wrong with Reman stuff, it has a lifetime warranty too
Looky Here! Price is right!
Lifetime warranty on this too....WHAT A DEAL!!!
A few salvage yard wires w/ connectors, Butt splices, and you are in business!
AS FAR AS THE DISTRIBUTOR SWAP--I CAN EXPLAIN THAT REALLY EZ, SO THAT YOU WILL NOT HAVE TO GO THRU THE "FIND TDC ON THE COMPRESSION STROKE" PROCESS...I CAN MAKE THE SWAP EZ, IF YOU WILL NOT MOVE IT/ REMOVE IT, TILL I EXPLAIN!
AS FOR TUNING STUFF YOU WILL NEED (MAINLY TO SET IDLE SPEED AND GET TIMING BACK TO SPECS....THIS KIT IS AVAILABLE AT "HARBOR FREIGHT" FOR LESS THAN $40
INVESTIGATE THE SITE...THEN INVESTIGATE CJ5 & 7 FORUMS
I WILL HANG WITH YOU AS LONG AS IT TAKES...JUST DO YOUR END AS "KINDERGARTEN-LY INSTRUCTED"...WE WILL GET ALONG FINE---NOT LIKE OTHERS ANSWERING HERE, I'M ON A CRUSADE W/ THE CJs---NO FAST, GET OUT OUTTA HERE ANSWERING FROM ME!!!
FREE GUIDANCE--REAL PICS--REAL EXPERIENCE...............
HOW CAN YOU GO WRONG?
I have already begun, assembling a partial EXPLANATION wiring diagram for you to go by...IT'S NOT COMPLETE, I HAVE A BIT MORE TO ADD TO IT...I'LL GIVE YOU A GLIMPSE, SO YOU WILL GET INTO THE "MODE"!!!
