double hung window locks / stoppers

A quick learner from Bridgeton NJ says:

Sorry to see that your storefront is closed and that you can only order online. I bought parts from the store when it was open and used them . They worked flawlessly.

I think I can use 90-077A along with 90-177. I need 15 locks in white the keepers on my windows look ok.

As you can see I need window parts now can you give me the best fit type?

There are no markings of any kind. The measurement is 2 1/16"

This looks more like our 90-161. Check it out and see if you agree.
A quick learner from Bridgeton says:
I believe 161 will work but does not have the alignment dimples like the locks I have. The 90-177a does that is the only reason I am asking . I should be able to use either or as both are the same measurements 2 1/16" and 7/8" for the screw alignment correct?

I meant to say i can possibly use 90-077A. Not 177
A quick learner from Bridgeton says:
Could I use 90-077B. That is the one I think is a litte sturdier ? And looks vey similar .

It's possible, yes. It has the same dimensions as the 90-161, it's just that the two are a different shape and I'm not sure if it will fit well on your sash.
