I'm sorry what a bummer. I don't know if AMI is still making the kits? I couldn't find it on their website just now, but when I googled "AMI M49" I found this page:
http://www.tab-funkenwerk.com/id183.html
So you'll prolly have to call them to see if they are still making them (785) 697-2257.
Also, Ben Sneezby is doing a run on M49 bodies which should be fabulous, see thread here:

There are a couple other initiatives right now too:

and

I am in on the Aputis bodies, but be wary on this one (no offense Andrew!) because this is another long wait for the results. However, I pulled the trigger because I know a) people have received amazingly high quality bodies that they have raved about and, b) I believe Andrew is a great guy and I love his version. So I sent him my money knowing full well I might be in for quite a wait. Hopefully not.
Anyway, have you tried contacting Riggler directly or perhaps Tskguy here on the forum? Dumb question probably, but a thought.
