Hello. Is this gap between the hub and brake plate normal? Thanks.

Well there obviously has to be 'some' gap there .

Does it all fit comfortably withing the fork gap? If you feel you have to physically splay the forks it's probably not right.

It fits OK between the forks, but it does appear that the fork spacing on the non-brake side is not as wide as that on the brake side. I had a T350 and I think the brake hub also had this gap, but am not 100% sure. There is a bushing pressed into the axle bore on the inside of the brake plate that is not flush and I believe that is what is keeping it from seating all the way. Don't want to start grinding away on it though I until I'm sure its a problem, otherwise I might have a bigger problem!!!

As grumpy56 said, make sure the wheel bearings are fully seated.
Also make sure the speedo drive is properly engaged.

Jabcb: Does your 72 380 have that gap between hub and brake plate or is it flush?

My 72 GT380 has a GT550/GT750 4LS front brake.

The 72 GT380 front brake is similar to the T350 front brake.
Just checked the gap on my 69 T350 & it’s a lot less than your’s. Looks to be around 0.04 inches.
