28 oz flywheel question

[VARMINT]

I have a 302 that I'm putting in my 65 ranchero and I need a flywheel for it.
I know that it is a 1978 motor so that's no problem but I keep seeing people mention flywheels that are tapped for metric bolt and those that are tapped for inch bolts. I already have a pressure plate so my question is this: are there inch dimension and metric dimension blot circles for the pressure plate oe are they both the same?
THANKS FOR ALL HELP

Varmint,
I just had this conversation with Mike Forte, Forte's Performance Parts. All of the major, quality flywheels are 8mm metric bolts, as is the Ford line. Two big Chinese suppliers (CAT is one) have flooded the market with cheap flywheels, and they all have 5/16-18 inch dimension bolting. It appears that people are dumping the Chinese flywheels anywhere they can - overall quality is not good. While they are stated to be SFI certified, other critical products in the power generation industry have been found to be no where near the quality stated, and there have been catastrophic failures, and fatalities as a result.

To answer your question, I believe the bolt circle is the same. However, I will not consider one of the inch dimension Chinese flywheels - I value my legs.
