Alignment lugs to dertermine lock replacement?

A quick learner from Philadephia says:
Looking for this identical lock and keeper set style, but *with* alignment lugs. Do you have this for an exact match or should I go with 90-177 and 90-077A instead? Thanks!

Alignment lugs are often difficult to match.

I think it's sometimes better to match the screw hole alignments.

Thanks, Paul. I decided to forgo trying to match the lugs and just went ahead with ordering the 90-161 lock/keeper set without lugs. The screw holes and lock profile seem to match my existing hardware almost perfectly. Hopefully will be a breeze to install and not having lugs won't matter much. Thanks again!
