Can one or both of you guys (Willwoods, or Boxline) take a micrometer to the crossbar of your Skyway bars?
when you have a chance 
.
I have a set of bars here looking very similar too, same knurling pattern as Boxline's bars (above), but I think my crossbar may be a hair thicker. not positive though - photographing bars can be very deceiveing..
- Bars are 28 1/2" wide
- Rise is 8 1/2" (or just a hair taller)
- Crossbar is 0.74" thick.
- each Knurl is 0.5" wide (with a 0.95" width gap between them)
- No stamping on the bar, anywhere.
- There is also
No Seam on the inside of the bar tubing.
- Extremely lightweight at : 1lb 9oz.
Any Ideas? could they be Skyway?
(did GT ever have knurling like this, possibly in 85 or so?)
