after consulting with some fellas at Vans Airforce,,, I figured I would make a fixture for my DRDT to allow for tight space dimpling.using the tool I purchased from Cleveland Tools, I fabricated a plan.went to Cdn tire, bought some steel and created the fixture after a bit of trial and error. a 3/4 inch block seems to work well, then I bolted the tool to the block, then the DRDT and voila!a nice tight quarters dimpler.
