Default Alternator bracket seal BMW vs. URO part

What is your suggestion with this seal, replacing with BMW original part or URO part?
This seal is BMW p/n 12317507808
Also bracket 3 front mounting bolt holes have adjustable bushings, so what gets torqued first these 3 bolts (red arrows) or other bolts (blue arrows) ?
I'm noticing many posts where bracket has cracked, most likely due to these 3 bushing not being adjusted properly.

Hi Roadmax, excellent question. Here are the installation instructions for Viton™ rubber Alternator Bracket Gasket 12 31 7 507 808-PRM (cars with Oil Thermostat) or 12 31 7 507 807-PRM (cars without Oil Thermostat):
