[LT77 in Series III 109 with 200tdi]

Hi, 

I am running a 200tdi in our 109 and want to upgrade the gearbox. The 200tdi is sitting on the origional engine mounts. 

I do not want to move the engine 4inch forward. 

So let us assume I will use a defender short bell house  , not a Stumpy, a defender LT77, an Ashcroft converstion kit and finally the standard series transfer case.

Am I correct that the HI-LO and 2wd/4wd levers will have to be slightly altered to keep them on their origional lications?

Does the main gear lever fit the series location or doe I have to modify the cover?

As to the gearbox crossmember, I am planning to cut the standard member away and place  a leightweight or RR bolt-on version.

Obviously, the propshafts will be modified as well. 

 

Am I overseeing any pitfalls or other please do not's or you will regrets?
