I know this topic has been a constant theme but I really need some help.

The problem I am finding is that there is so much conflicting info that I don't know whats correct.

Bike specs: 1978 cx500 currently with factory front fork and brake.

I want to upgrade to the dual disc brakes and beefier forks.

I found a guy with a 1978 Honda Goldwing. He said $150 for Front wheel/forks/ brakes/ triple clamp/ bar and controls with clutch cable.

Any advice would be greatly appreciated.

Will do, I just signed up yesterday so I haven't really played with anything in my profile yet.

Not so sure

The 2 lists I posted show contradicting info...

The first list shows Upper: 26 x 48.5 x 15, 2nd shows 26 x 48.5 x 15.2

The first list shows Lower: 30 x 50 x 14.25, 2nd shows 30 x 50 x 14.4


First list shows the same bearing size for the '78 cx500 & '78 gl100 Goldwing

2nd list shows the Cx500 only compatible with the '75-76 GL1000

Sorry to be a pain. If anyone could clarify any info that would be great!

Obviously I know most parts for front end conversions are compatible with modification such as welding/machining but I am hoping to pick up a direct bolt on setup to save some aggravation/money.
