Thanks guys! Here's a long overdue update.
Got all 4 wheel hubs installed. These are super light compared to the originals.
Wheels and tires came out nice, it doesn't looks as much like an F1 car now but function over fashion. I had to buy longer wheel studs to accommodate the new style of wheel.
Installed an oil catch can.
So far I've only driven it the one time. I found a hairline crack in the clutch cover which was slowly weeping out the fluid so the hunt goes on for a vintage horstman clutch cover. The gas tank seal at the filler cap also has a leak which could leak gas out during cornering so that will need to be replaced as well. I have a kill switch button I need to wire in as well. Unfortunatly with my Z undergoing a motor swap the Kart has been put on the back burner for now but expect go pro racing vids of this guy in the future.
Here's a VERY informative video I found on youtube regarding setting up a kart..
