According to @BSinvestments He bought the full cage from DF and welded it his city chassis. The guy I bought it from told me a bunch of crap, but he also said you can add a full cage if you wanted too? I wish there were more Goblins close to me, that I could try out, since I'm tall AF....?
BTW, at 6'3" and 280 lbs. getting in and out of the track frame with standard side bars is not overly difficult. It does require some practice, articulation and specific places to hold onto (and a removable steering wheel is a must have), but even with arthritis it can be done.
Welder came over this afternoon and started mocking the full frame up for me!
He raised the halo about 3-4" higher and racked the halo downwards to the hood, it actually looks pretty cool like this!
He got the caps/plugs removed off the standard frame, but he didn't have the right size to put a slug in it, so he'll be back tomorrow.
He got the front bars cut to fit over the "future slugs" and front of the halo.
He's also going to add some larger gussets in the rear tomorrow as well!
Got some pics, but they're dark. I'll have better ones tomorrow.
