If you cant get the A frame to fit then have a new one made up, i know a guy local to us who's just made a custom fit double A frame for my 4.7 searider and its supperb, low enough to still fit in my garage and is shaped around the tubes not the straight up type, plus the price was very very good
Let me know if you cant make your A frame fit or if you want to know more
