This is a 1985 Mac 25. I used 90lb/20 inch struts.
The position is pretty much determined by the location of the supports, it has to fit in between with the top down. There is room there for the 24" units and it will pivot to a position where you have to push the top forward then down, someone falling against it isn't likely to collapse the top. Vwjon, does the top go all the way up with those struts?I see that yours has quite a bit of rod extended when closed. How did you decide where to position the bracket on the top?
