Where to find correct pushrods?

I have 1965 G15-CS with stock intake and exhaust valves (best I can tell...both around 3.92")

I'm in need of pushrods, however. Andover Norton lists pushrods for the desert sleds at 8.28" and 7.4", which more or less match what came out of the bike (aftermarket skinny alloy things, one with a shattered cup.)
----
#1, Can anyone help me confirm that the lengths I see on A-N are correct for my application?

#2, does anyone know a source for a complete set of the correct pushrods? (A-N lists out of stock for the intake, as does everyone else I can find; I did enquire w Norvil already and waiting on an answer...)
----
I already ordered a set off an eBay seller which were listed as the correct year and model but they were Commando length...I'm asking him if he has longer ones available but he hasn't been super responsive.

Thanks, everyone!

I get a lot of N15 parts off MachIVmotors on eBay. They are located in Appleton Wisconsin US

Yeah, that's where I got the wrong-length pushrods. He was terse in his response asking if I could exchange them for another set if he had one of the right length and hasn't responded to further inquiries about any of the several sets he's listing, alas. I hope he does have them; his prices are good.

Have a look at www.ebay.co.uk/str/norvilmotorcycle. They have a couple of second hand sets up. If in doubt, ask them.
I was looking at some rockers a little while ago. I asked and they put a set together for my N15.

Norvil has them, at a great price no less! I was waiting for a response bc the lengths weren't listed on the site.

Anyone can help me confirm the lengths before I pull the trigger? I mean I know they'll work at least somewhat correctly because they match what came out of the bike...but I want to make sure it's optimal.

EDIT: Oh I didn't even see your link was to their own eBay sales site. I'd written their customer service. Thanks!

Optimal ?? You building a race engine?

Those pushrods lengths you posted are shorter than the skinny sticks I had in my P11 750 engine.

Bottom of cup to tip of ball 7 3/16" and 8", overall length 7 9/16" and 8 5/32" Something tells me what I have are mixed up pairs or for a Commando. I think what you have is good, but I'm not exactly the right person to confirm what's right on this site.

Anyway, I use theoretically stronger push rods that are a bit longer than they should be because I prefer to use lash caps and don't want to wait around for someone to make me a custom set. Do the slightly longer pushrods make my engine suffer? Not that I am aware of twisting the throttle. And the lash caps keep the adjusters in the rockers from grinding down the tips of the valve stem. By the way, my experience is KW black diamond stellite tips wear quickly without the lash caps. Maybe I should use less throttle.

Hah, I'm building, hopefully, the opposite of a race engine. I just want it to last and have as few problems as possible. My understanding was that pushrod length was key to maintaining valve timing.

You bring up a point though --i am measuring overall length; should this be measured from bottom of cup to tip of ball?
