Standard Open cross pin shaft for four pinion design for GM 10.5" 14 bolt truck.

Very Easy

Good and easy

I have a mini-maxx that is a Spelab unit. I was skeptical that it would fit the mount, because the mini Maxx that this mount is designed for is a kit from a different company (Bully Dog?). Thankfully, it worked exactly as I had hoped, and it fit the mini-maxx perfectly. Maybe I need to understand more about these kits, but it seems to me that KT Performance would sell more of these if the unit was relabeled and marketed them as suitable for a number of kit manufacturers that used the "Mini-Maxx" It would also make it easier for web search engines to find this exact product, because I found it using the syntax of "mini-maxx," and having no idea what "Bully -Dog" was, or that it might lead me to the product that works perfectly with my Spelab Mini-Maxx! Hope that helps!
