Fitting an E36 TDS into a classic car - making up the engine mounts now to receive the standard BM aluminium engine `turrets`.

1) They appear to be about 12Deg off horizontal - can anyone confirm if this is correct ?

2) Another question - are engine and gearbox mounts both at the same height each side of the chassis? (the gearbox crossmember is asymetrical presumably due to asymetrical floorpan- but the rubber mounts themselves appear to be at the same height as each other - as do the engine mounts)

If so easier job !
3) engine rocker box - is this usually horizontal/ level i.e. roughly spirit level bubble in the middle longditudinally/ transverse (assuming level floor/ suspension etc) ?
