I modified a pair of Wolf arms to use on Gog. (The image isn't real good) but what I did was cut off the bottom of the internal tube, slotted the side of the housing, then slipped the SIIB hinge through the slot glued the two housings together with 2 part epoxy glue (tape), then inserted the original spring and clamped it up with a new stepped washer and a stainless socket headed cap screw.
You may be able to use the Wolf arm, but fabricate the SRV hinge bracket and affix the top of the Wolf bracket to your bracket and clamp it up in a similar method to Gog's.
