New 360 Flywheel...

Need some quick opinions...

Looking to buy a flywheel because I'm swapping to a manual 4 speed. I've located one that is a few years old, but never even out of the box. It's Napa brand and was originally purchased for his 1980 Dodge truck.
It has 143 teeth.

1 - is this the one I need for a 77 block 360 w/ a A833 OD that I'm using in my Duster?

2 - is $120 for it a good price?

Thanks!!
