Starter question

This doesn't pertain to an LA or magnum or a /6.
This is a newer truck/engine.
12 ram 1500 4.7
My original one is going out, I get that occasional "dead spot" when I hit the key that may happen twice today and then not act up for a week kind of thing.
I bought a new reman from eBay, replacement is a Lucas brand which has been around forever so I thought it was a safe buy. New reman, and half the price of any parts store in town.

I put it in and went to hit the key and the starter spins but the bendix makes no attempts to spin out and contact the ring gear.
One thing I noticed when I went to reconnect the wiring was that the small terminal (a plug in on this unit) is above the 2 big lugs where the original one is below the big lugs.
I contacted the seller and they surprisingly immediately issued me a refund and said they don't list one for my truck even though eBay listing said this one does ft my application.
They said "no need to return" since I did install it.

If this were a starter for an older model car/ truck I'd say it's almost like they forgot to reinstall the fork from the solenoid to the bendix.

My question is, although I didn't think much of the flipped position of the small terminal on the solenoid when I put the starter in, I'm wondering if I simply unbolt the solenoid and the other big lug (the wire that goes thru the starter body) spin the solenoid 180* and reconnect, if that might be all that's wrong with the new one? I'm thinking the constant hot needs to be on the other big lug as compared to how it came to me, for it to work right and energize when power is applied to the small lug?
