Okay, I don't wear shoes all the time, drink more beer than wine and I AM a product of the North Carolina school system. What does 114.3 mean?

I am in the northwestern North Carolina mountains, right up against the Blue Ridge Parkway. Lawn chairs are in the shop and always time to talk. Drop in any time.

Positional Crankcase Differential. I'd say no. For an MGB it should be 119.7

I believe the question is about the diameter (in millimeters) of the bolt circle for the studs/holes for bolt on wheels.

PCD = 'Pitch Circle Diameter' = BCD = 'Bolt Circle Diameter'.

Or he could be looking at a wire wheel hub and trying to identify if it is a B.

The MGB has a 4.5" PCD, or bolt circle

25.4 mm = 1 inch

25.4 x 4.5 in = 114.3 mm.

114.3 mm is a popular PCD for Japanese imports. Unfortunately, most modern cars using this PCD are front wheel drive, and their wheels have too much positive offset to fit on an MGB without fouling the suspension.

Hey thanks.
Sorry, I should've put the mm after the PCD.

That was for a set of old skool mags listed in a local auction.
I re read the listing - they're "13 = no good for me anyway.

As you were, Paul ;-)

Yeh, 4 stud 114.3 are probably datsun, maybe cortina, 13 inch only.

I had old school 14 X 6 mags 5 stud on MGC hubs.

I preferred the look to the wires.

I may even put them back on.
