Tom Manley has provided some kart building plans from American magazines of the early 60's
This one is for a "Road Going" kart - good luck with the Roadworthy - but has lots of useful details for restorers.
Another kart plan from Tom.
This is a racing kart but does use a pre-bought body/seat unit. May be of value for the details of many of the components used.
