If you followed the forum thread above, I made a batch of 110 rear step bumpers which was a copy off of the 1993 110 NAS rear step bumper. Anyway I did end up with the jig and one bumper. I owe a forum member a bumper (as he put a deposit on one and will get square with him though he has not mentioned it)
The forum member that was going to take on production is too busy. So I am offering the jig and bumper up for sale should anyone want to purchase the bumper and Jig and run with the project as these bumpers I believe are class 2 and will bolt to a ROW 110 truck as well as 110 NAS. Price as per forum rules...I would like to get $1,200 for the bumper and Jig. PM me if you are interested.
Note: you can also use the jig to develop a ROW 90 Sep bumper as the step and front portion (including receiver are the same) you will just need to modify the frame mounts as the 90 NAS was set up to bolt to the Petrol Fuel Cradle which the ROW 90s don't have.
