I would prefer this, but the other would work. I bought a set of OEM Hardbags without realizing I had to have rails to mount them. So I am looking for a cheap fix till I can afford to pick up a set of rails.

I saw a bike at InZane where the above mounts (HONDA OEM softbag mounts is what I think those are) were used to
mount some nice Kawasaki Vulcan hard bags to a Valkyrie. He did a nice job of it, and I think if you do a good enough job
to end up with something that is usable, you might not consider it to be temporary. Of course, since Vulcan hard bags and
Valkyrie hard bags are very different, you might find it doesn't work at all... I can't imagine doing it without drilling holes
in the Valkyrie bags... blegh... Probably your best bet is to wait to find OEM mounting hardware... it goes on eBay fairly
regularly for $200-$250...
These just went for $214 (the guy sold the pans separate for around $20...

These (mounts and rails) just went for $535...

So... the OEM hard bag mounts and OEM hard bag rails are different things... Both of these Valkyries
have OEM hard bags mounted with OEM hard bag mounts, one of them has OEM bag rails...
