'65 is indeed 6V. All the wiring is part of the body, not the pan.
So, you wind up with the 6V headlights, tail lights, instruments,
even the horn.
In the bargain, you get a steering column WITHOUT the safety
If the '70 engine is 12V, then the body needs to be converted to 12V.
There are NO wiring changes needed; just replacing lamps, etc.
See the 6V/12V article on my web site.
The body mounts the same except for the rear support brackets
(inside the rear wheel wells). Those you may need to move.
A 1600 engine is a tight fit inside the '65 body but it can be
done by removing the muffler. Don't try to drop the body
on with the engine in place though.
'66 has a 1300 engine which uses the same size muffler as 1600.
The '65 had a 40HP 1200 engine with smaller muffler and head spacing.
You can't install the 1600 engine into a '65 with muffler on.
The engine will fit (barely) with muffler off; then bolt one
So........you can drop a '66 body with a 1600 engine in place. :-)
The amount of experience on this news group is mind blowing. Thank you
for all your information!
I have decided not to do a body swap because of lack of electrical
components on the '65 body.
I have posted the car up sale/trade on thesamba.com
Many people have offered to trade me parts on my 1970 bug.
