thanks for that i have been searching but not to hard ,
your pics and info i have found are a great help ,
thanks !!!

i have searched and is it true that i should use 180b engine crossmember?

yes its true. you'll find a 2nd set of holes for the 180B xmember when you remove the standard one. you'll have to trim a little off the rear edge of the 120Y's castor rod brackets to allow it to fit though.




what about gearbox clearance in the 120y tunnel with the l series box ?

heaps of room.
