Thanks Slow, but StinkyFab's website says they closed for 30 days on May 19 so no help there unfortunately.
I did find and buy what appeared to be a set of OEM brackets on eBay, which were delivered today (will need to open box and verify correctness once I get from work tonight). I did try to confirm via the "contact" system that I read the ad right, but didn't hear back. Since the ads claimed only 3 of each on hand, figured it was safer to just buy and return later.
On the Ironman front, last I talked to Andy on Monday was that the timeline he originally gave me (him getting laser cuts Wed/Thurs this week, 1 day to weld/ship, 2 days transit to NJ) should still be in force. Will probably touch base with him this afternoon just to get an update in case they were focused on getting stuff out the door rather than sending update notifications.
Oh, and Chris - I did call Froehlich last Friday. Left a voice message with my question, but have not heard back (and at this point I don't really expect to)
Now I just need my mechanic to be able to free up a lift in time to do the install - I don't have a level-enough spot to work on the Ironman brackets in my driveway (or giving how it delayed my doing the rear brakes, possibly luck with the weather), and if I have to go with the OEMs I'd need him for the welding anyway.
Still at least a 50% chance I'll be looking for open seats this weekend, but won't know for certain probably until late Wednesday. Not my first choice for how I wanted things to go for this event, but riding passenger is better than not going at all...
