Chassis change 90 to 110

Hi
Im thinking of a new chassis and wondered what is involved in going from a 90(2.5N/A) wheelbase up to 110. i know i need a tub, propshaft, fuel tank relocation and loom can i get away with the original axle or must it be salisbury? id rather keep the landy i have now as a base as i have started with it.im assuming from the gearbox mount forward is the same on 90 and 110s? all advice appreciated for making decision.

well it would need re registering for a start……just sell the 90 and buy a 110

op2:

option 1 - buy a 2nd hand bare 110 chassis with ID, put all your parts on it + any 110 only parts, sell your 90 chassis & id and any unneeded parts on ebay
option 2 - buy a full 110, fit any parts from yours which are nice/upgraded, sell yours

whats not an option... sticking your 90s id on a id less 110 chassis you got on ebay, if you get pulled and a check takes place expect to end up on a Q plate as a minimum

Buy a knackered 110 and rebuild it using all your parts. Sell what's left including your chassis with ID.

To answer one of your questions. yes they are the same from the seat box/gearbox mounts forward
