G'day all.
I'm after a flywheel for my 253 motor. I've been searching wreckers and online, and doing some research. I found a NEW one available online for a reasonable price, but I'm confused about the ring gear tooth count.
I'm looking at this one: http://www.ebay.com....tm/131280341910 which has a 158 tooth ring gear. I have read that Chev is 163 and Holden is 153... so what is a 158 tooth ring gear? A bet each way? Is that going to fit with a standard M21 box and bellhousing? Will it chew out my starter motor gear?
Cheers.
