They're pretty much all based on 165R-15.
1800 pounds.
If no body work was required from $800 to $5,000 depending on the quality of the paint you want.
2 quarts if you paint all of it. Id buy a gallon to be safe.
2.5 litres.
2000 lbs.
No, the hood will not fit. 1965 is pre-Super Beetle; 1973 is post Super Beetle. The 65 hood is going to be much more narrow and arched then a Super Beetle hood or anything past their early transitions to the Super beetle which started to transpire in June of 1971
Two and a half quarts.
2000 lbs, give or take a 100 lbs.
Meal worms are much smaller and softer than super worms. Also, super worms in beetle form are much larger and malodorous than the beetles that come of meal worms.
Yes, since that's a tautology. Unless you mean "would additional seats fit in a vehicle without taking the original seats out first", in which case it would be a pretty tight fit, but you might be able to get them in the back. There isn't much room in the "trunk" (which in a '74 beetle is actually in the front), and I doubt you could get them in there.
WAY too much free play back there.
