Bimini here too
I had an Ameriseam made last year for my 1992 H23.  They did a great job.  If you have a split backstay, for some reason, it is not included in the original pattern they have.  I had to call them, take additional measurements they asked for, and send it back.  They added velcro/zippers to allow the split stay to go through.  They were very fast and it is great.  I can sail with it on and it stowes against the backstay.  Good luck
