Ive buy a manual setup from a guy how had a 86 camaro....and tomorow when im gonna put it in i see that my new flywheel had a biger bolt patern than my crank...is there flywheel for 1 pieces rear and 2 pieces rear??? and if i buy a new flywheel...it fit on my clutch and pressure plate that i already had?? and...the number of tooth on the flywheel how i know what to buy??? plz help me....im so confused a this time

 

Yes there are different flywheels.

Yes your clutch will fit, if it's for a Camaro / Firebird with a V8. (assuming of course that you're working on a V8, sounds like it)

You need a 12.8" flywheel with 153 teeth for a 10.4" clutch. It's the stock flywheel for a 86-92 305 5-speed Camaro / Firebird. There are actually 2 stock ones that will work; one is lightweight and was used on L69 and TPI motors, the other is heavier and was used on the base-model LG4 and TBI ones.

 

yes bolt pattern is differant for one piece and two pice crank seals, also the one piece seal cranks have a dowell to locate the flywhhel. the reason is when they went to the once piece seal mass was removed from the flywheel mounting flange and to make up for it weight was added to the flywheel. this tends to make people want to think the one piece crank seal engines became externally balanced when in fact they remained internally balanced.

 

Big thnx to you guys!!! now....i want a 153 tooth flywheel for 1 pieces rear main seal!!!
