I’m in need of a jalousy side window for my 1974 13 ft. Boler (left side window when facing rear).
Welcome to FGRV Carol. Just for future reference, curb side or street side works well as it doesn't make any difference which way you're looking at it .
If you haven't already done so, you might post your question about the jalousy window in our "Problem Solving" forum... More people might see it there.
