The mock-up went pretty straightforward, just eyeball it and cut a little here and there! It took several cuts on the upper rails to get it cose. If you do one of these projects, take your time!Next time we'll cut 2" off the new hardtail sub-frame, to allow easier matchup with the Sporty frame. Slugging and welding on the stubby upper bike frame rails will be tricky. We may be adding a gusset to increase structural integrity!
