Will a stock 99 Explorer 5.0 flywheel work with a Bronco C-4?

[rjrobin2002]

I pulled a 99 5.0 from an Explorer and got the flywheel also. I know it is the correct balance, but is it the correct diameter and tooth count for the C-4? I will be using the Explorer starter also.

Diameter, correct
Tooth count, correct
Balance, for the explorer engine that is, correct.
bolt circle, maybe. broncos came with 2 different bolt circle torque convertors. The no longer serviced 10.5" bolt circle which won't work and the 11.4" bolt circle that will work. Get the torque convertor with the 11.4" circle to replace the 10.5" if that is your problem. The correct flexplate (164 tooth, small bolt circle) is an obsolete part for the old balance engines and never made for the new balance engines.

I've seen the 10.5" in '73-'76. Could be some in '77 I guess. You could take the inspection cover off and measure from center of converter stud to outside edge of teeth. 10.5" circle would give you 1.88". 11 7/16" would be 1.41".
