Wheel shopping: wide glide -vs- narrow glide; HELP !

[Clutch Cargo]

I got a new girder that calls for a narrow glide wheel.  '84 - 99'     How do I identify a wheel as being narrow or wide glide when on eBay?     Need a 21", 40 spoke, chrome, 3/4 axle, single disk and a caliper / disk combo.

thanks.

Step right up !   Anyone ?

You need a wheel off a Sportster or Dyna narrow glide. The wideglide or softail wheel/hubs will be too wide to fit.
