Sorry, only just seen the reply.
Doors, bulkhead and seatbox disconnected and me and a mate removed the 110 van body. Wheels were off so it was lift-shunt-lift shunt etc until it reached the balance point at the rear of the chassis and was then tipped up on its end and shuffled out the way. The csw tub was built up in pieces on the new chassis as the floor was rotten. We even fitted the 2.5 nad back in without a crane using scaffold planks and trolly Jack's, no head or bits on it. I thought my eyes were gonna pop trying to get it on to the front cross member.
I got an actual hernia around that time, not sure if it was doing that or carrying a 2300mm x 600mm double radiator into my new extension in 1999. I was even building straight after the op , wasn't going to sit around for 8 weeks off work(paid) doing nowt. Got another hernia now but that was from a fall from hight and the nhs won't fix me now cos I'm too old and carbon fibre is expensive or summit.
As for the roof rack thing, depends on the rack and how many clamp points. My roof rack weighs a ton and that rack was fitted to my 109 and I brought the new 110 chassis back from the galvanising plant on it. That was a bit silly but it was around a mile and a half away and I went via a quiet route. No damage to the 109.
