I got the black out kit for my TRDP, can't use the SR5 portion.
I figure it will survive a double stamped envelop trip anywhere a USPS letter will go... If you want them and think you'd like upgraded packaging or whatever that will be on you to figure out how to finance it.
PM me your address and I will put it on the envelop and drop it in the mail next time out.
Cheers
