Substitute for Andersen Roto Lock 1959 to 1981

We have Andersen Beauty-Line Awning Windows (1957 to 1979). Andersen's parts catalog PAGE 13 gives a part number of 0333808 for the Short Arm roto lock operator.

Can your swisco Product Code: 39-390 substitute for that Andersen product. Your product has 2 extra crank mounting screws which we can work with. I'm wondering if this latter model year product has the same clearances and is just different in appearance but fits in the same recesses.

I did purchase the 39-390 and install it in place of our Andersen Beauty-Line Awning Windows (1957 to 1979)-[Andersen part number 0333808 for the Short Arm roto lock operator]. It worked great. Had to drill 2 additional holes and replace the sliding rod on the window itself but the fit was no problem.

Thanks for the follow-up A professional from Wisconsin. I am going to try this myself. Andersen wants $200 for the kit...
