OK, I thought of this some three years back. And I had a few made up "battery Legal Mumbo Jumbo" plates made up. And all I got out of it is a bunch of "that will be points off" BS from a few of our forum experts. REALLY!
And still, this pops up from time to time. You want them. NOBODY makes the group 24 case and yes, there is a "topper" that has a decal that, in my opinion, is not even close.
So, let me start by making a list of who is interested in the legal Mumbo-Jumbo plate you can glue to the top of a battery, or the top of the topper, or anywhere else. PM me.
Price? I am not sure yet, but with postage likely about $35 to $40 each. And, if you have the time, I believe the letters can be removed from the mounting plate and glued on, eliminating the plate.
The folks who make these said they would rather not made them one at a time, so, this will be a one shot deal like what Nic did with those nose wiring guide he had printed for the 67 center high beams.
