welcome to the 'bolt andy - like webe sez, we like pictures!! especially of more task force trucks
in 59 the 4 speed was pretty common as the standard trans - V8 was an extra cost option, tho if yours isn't a 283 it'd be a later replacement - the original V8 mounts were off the front of the block, and if the frame has 2 riveted on brackets that the motor mount pegs sit on, it's original, if they're not there [or are bolted on] it originally had a 235 I6
