Lurepartsonline has a do-it keeper that is 7/8 inch long, it is a little hard to find on their website. I believe it was on the same page as the new minnow head jig mold with the wire keeper. I did a search for wire forms and it didn't come up , but latter I found this mold and at the bottom it had a place to order wire forms. I actually wanted the wb400, I believe the one they sent me is a wb800. I bought 400 of them about 2 weeks ago.
They didn't have the new mold listed with their other molds either, You just have to spend a little time going through the jig molds to find it. If anyone has trouble finding it let me know, and I will look up the part number.
