Unique Cobra questions

Now, I've never crawled under a Unique Cobra, so keep that in mind. But a switch from bolt-on wheels to true pin drives is not a quickie task. I'm betting the track width will require a chop and weld of the Jag half shaft. ERA's outboard braked six pin system does. That's not as hard as it sounds, but you have to cut the yoke, turn down the shaft, press-fit and weld. You can read about it here: https://www.erareplicas.com/427/shorten.htm But what might be a little more challenging than that is configuring and fabbing your hub carrier, hubs, brakes (if you want outboard). That is some serious modding. Cobraracing sold hubs and carriers at one time, but I believe ownership of that outfit has changed hands. ERA stuff, if you even got a hold of it, is not going to work for you. In fact right now I'm told even ERA buyers can't get ERA rear uprights. Here are pics of the Cobraracing stuff, there are bound to be others out there that will fab it for you. Now, if you can live with 5 pin adaptors those will fool most people. I couldn't though, I had to have true six pins.

Patrick, thanks for the info on that. I saw on the Unique website mention of cut down shafts for pin drive wheels being an option. But I also saw this link from Trigo that looks like they have an adapter to make it work, I also see their 6 pin vs 5 pin wheels have different backspacing. I think I could live with 5 pin vs 6 pin, they look the same from the outside, correct? I want an authentic look, but mostly only concerned about the interior and exterior, not so much under the hood or underneath. I also don't mind the inboard brakes, I doubt I would ever track the car.

Check out the link below. Thoughts?
