Richard, thanks for your reply. Yes i have used the L16 sump and pickup when i got the motor rebuilt. The car came with an L18 & 5 speed in it, all i did was remove the L18, and bolt in the L20. I will b using twin 40mm delorto's off the side, and what the bonnet is catching is the dome for the timing chain at the fron of the rocker cover. At the moment i have about 10mm clearance between the front of the sump and the cross member. I also have some extractors from and L18 i think that wont fit between the gearbox and the gearbox tunnel in the firewall/floor.....
