Saw the thread awhile ago, just re-read it & copied all the pertinent info. I like the Renntec version but for my needs I like the flat surface instead of the renntec 'ducktail' rack. For one thing, it makes mounting a tail trunk much easier when the rack is flat.
I also heeded Sean's advice to swap the entire rear fender/grabrails/taillight & turnsignals ***'y. (and luggage rack/sissy bar, if you have it). That looks like the easy method to swap the entire ***'y. quickly with a minimum of screws & electrical connections. Looks to be about 10-15 minutes to accomplish. I still need to find some grabrails and the misc. brackets for them, including the underfender bracket, the and the small brackets for the rear reflector area. I have a fender. Come to think of it, I would need a light & brackets too. Then it would be 5 nuts/bolts & the plug-in electrical connectors to remove/replace.
I just took-off my stock sissy bar & grabrails, stock luggage rack brackets, my stock flyscreen, handlebar clamp, handlebar riser, front turnsignal/speedo mount, complete triple trees, & misc. small brackets to drop tomorrow at the powdercoater's. Everything is going to match my side scoops which they recently did for me in silver metallic & clearcoat.
