For sale is a Dreamworks Pro-Link nose strut. The unit measures 6-3/4in. from the top of the strut to the center of the axle. Included is a nose wheel that is 2-1/2in. in diameter. The upper mounting of the strut measures 1/2in. which goes into the retract unit. Elsewhere I have for sale a TamJets nose retract unit that would be perfect for this strut.
