Early Z Carb Chrome Bowls

I've ended up with these freshly chromed big nut Z1 bowls and would like to trade someone if they perhaps have a decent set of the originals? These are the 2nd iteration of these bowls, early ribless had removable choke brass bowl jets. Anyhoot, have to have good threads for the "big nut" and not beat to heck. I have the overflow nipples but recently removed them. I could remove the chrome but i thought someone "might" like the bling? 

I’d entertain a swap…. Tomorrow after work I’ll dig up what I have a see if they will work for you.

That would be super cool Matt!

Oops, it’s tomorrow after work and I completely forgot. I forgot that I forgot, lol

I can't even get close to judging You when it comes to time displacement!! Want some gauges my Friend!!

Lol when ever your ready. 

Found one set of two I know I have. It’s a 1473 set dated August ‘73. Not sure I wanna break them up. I’ll keep looking for my other set
