The intake looks like it's been opened up to 46mm, to match the Z/4 bolt isolators, definitely not 38s

Looks like early 240Z carbs, 220 or K14 manifold with Z air horns.....just like mine.

Where is the spring broken????? On the end???? Pull the trunnion off and have a better look.......bend a 90+ degree on the end of the spring and hook it back up. who cares if there is a little more tension. Or......as a temp fix just get a long spring and hook it up to the trunnion and or, (closer to the throttle body the better) until you can find the correct one.

My guess it broke and or came off that lower brass peg....................pictured here.

Did you check the spring behind the throttle trunnion.........?........

Ha ha....i did exactly the same thing installing my old Z motor into one of my trucks a couple weeks back......no cat litter though, dumped some planer shavings into the tire 'FTW'

Sure they do.....I've uploaded and posted many videos.

Looks like a pre '84........pretty sure all single cab 84+ US/Canada models had cab vents like this.....

That's "nomal" height and 35s won't clear. Wouldn't look as 'high ' if you slapped some fender flares on it..... .....and the cab vents .

Well....they don't ship to Canada either. There are other sellers.......found this in about 2 min. http://www.ebay.ca/itm/Weber-32-36-DGV-Manual-Choke-conversion-kit-fits-Datsun-510-610-620-Pickup-/271280922121?hash=item3f299a5e09&vxp=mtr#shpCntId

?????....Depends on the 4 cylinder. Those look like the early 240Z 46mm roundtops. The K14 or 220 intake will have to be opened up to 46mm.....and you'll have to profile a set of needles to get your A/F ratio numbers in 'order'.
