Sorry guys looks like I am going to have to pull this of the for sale/trade for now I am having issue's with my other corbin seat. I will hopefully get back to this sooner than later.
Thanks for the info, I have the box and the plate that it mounts to, just looking for the two bars/arms that attach to the existing bolts where the grab handle is? If you run across the guy making them let me know. Thanks Hank
