You need the LH mount off the motor (Series) cut he RH mount of the chassis, and weld the LH upside down.
I took both LH engine and removed both chassis mounts, moved my 2.5 forward 4-5 inches and welded them to the chassis.
I also am using an LT77 and LT230, I removed the series tc cross member and made my own mounts for the LT230, I can send you the patterns for these if this is what your doing.
This places the shifter in the center of the series tunnel cover, Im running E-fan and will make some custom linkages for the diff lock and hi LO
Hope this helps
