several ways to do it

but the first bit of advice is dont fuck around fitting a 8v compaired to the 16v there just is no comparison and the 16 is just so cheap it would be rude not to

use the a f16 or an f20 dont really make a difference

drive shafts there is 2 ways to combat

either nova gte inners with cav mk2 inner cv's but the cav innners are getting rare now
or you can use big block ones with big block hubs machined to go into the nova legs.

mounts just get a set of engine mounts from someone like chris astley

other than that there aint really much else
