Step 1: Fit Hubs

Since wire wheels use a center mounting point, a splined adaptor hub must be bolted to the stock hub. There are
three ways of doing this:

1. The stock studs can be cut down so only 5/16-inch protrudes from the face of the hub. If you’re going this route,
remember that the studs will need to be replaced with new ones before the stock wheels can ever be reinstalled.
2. The other option is to remove the hubs so that the stock studs can be replaced with shorter ones. A hydraulic
press is needed to install the new studs. (Hint: Moss stocks the shorter, wire wheel-spec studs.) Now the wheels
can be physically bolted to the hubs. Note that the hubs are threaded so that the knock-offs won’t loosen
themselves as the car drives down the road: The left-side hubs have a right-hand thread pattern, while the right-
side hubs feature a left-hand thread pattern.
3. Simply use a thin spacer the thickness of which equals the amount you'd need to cut down the studs.
These are Triumph wire wheel adaptors with such spacers.

PS - you might also want to note that you need to use special shallow wheel nuts so the adaptors don't cause
the wheels to bottom on the nuts instead of the bevel on the adaptors (regular wheel nuts hit the inside of the
wire heel rim).
