yes, they look exactly like mine... you could buy those, and get the new steering head bearings and any missing headstock parts from andover norton. You should also get new fork tubes from AN too. The rest of the front end you might find cheaper in bits and pieces used, but fork tubes should be brand new from a reputable source.
Sliders also can wear inside in an oval pattern, so used sliders may look like a great deal, but you may feel some slop when you're completely assembled. If you do go with used sliders, don't pay a lot for them...
Then I (emphasis on I) would pursue a disc brake front end which works with the early yokes the same as it does with later model yokes. My 70 model had early yokes and later model disc brake set up, (which is just a disc brake wheel, disc brake slider, and the related brake mechanism) until I changed it to cast alu wheels, an aftermarket brake master cylinder and a yamaha disc... (yeah, blasphemy is my thing)
I still run a 70 swingarm. It's not a problem at all. I wouldn't waste your money on a replacement just yet, You have a lot of other stuff that you need to buy before you go buying upgrade ttparts that aren't essential... No one here would ride my bike and say..... "Wow, I can feel that you have the less rigid swingarm on your bike!"....
** my comment about some parts on a 70 model wasn't to spark a buying spree on your part to upgrade every part like they were "must upgrades", but just to let you know that you have to make sure you buy compatible parts to your model, AND to be aware that IF you have to buy a part for your bike and there's an upgraded part from later models that fit your bike AND work better, it would be a better use of your money to buy the better part...
