I did fail to inspect the rockers/shafts before purchase, and that’s on me. I couldn’t have seen that they were different ratios until I got my calipers on them, but in the end you’re right; I failed to inspect them on site. I trusted the seller.
It happens. I’d by lying if I said I notice everything at time of sale. There’s been something’s I’ve missed, nothing really major and usually cosmetic. But still, it’s trust but verify.
