I have never seen a vertical shaft used . Good used side shafts are scarce around my area. You might start a thread for anyone that has used a verticle. I am looking at a full kit but new is $2,400. Install looks like a bolt-in for a G9. I can't weld in my garage anymore as the neighbors get scared. My '9 is going to be a deep smooth red with black trim and some alum. diamond plate. I'm going to leave the top off and look it over. If top is used I will paint it black also. Gotta get next to the Dolly for those pics
