Certainteed Casement Window tie bar guide circa 2003

I am looking for some replacement tie bar guides for my Certainteed casement windows manufactured in 2003. the only identifying marks are a crown molded into the lip that surrounds the tie bar and four screw holes, of which the outer two are used. width not including the screw holes is 3/4 inch and length is 1 5/16 inch, depth of stand off is 5/16".

any help will be appreciated!

Thanks,

Kevin
