Painless GM starter

[owner 84]

Hi, guys

I have been wondering what I should buy between two starters from Paniless. They have really good starters and they are trusted as I always hear that from some people.

I have GMC 1984 with 350 engine, but painless has a notification which makes me stop doing anything.

It is that(Note; the 51101starter is for a 168 tooth flywheel and the 51102 is for the 153 tooth flywheel. The 153 tooth is 12.85” in diameter and the 168 tooth flywheel is 14.125” in diameter).

which one is for 350 engine?
Do you recommend other brand that has stronger and trusted starter?
