Can you remove the bulb holder from the other side & see if it works in the bad lens? Unsure if the wiring is linked through the bulb/holder.
Need a voltage reader and find the correct cable & trace the wire back to the light that does not work.
Check the following
Handbrake drum. Is this tight? When the prop goes on is it still tight?
The UJs in the rear prop may have worn & need replacing.
Is the big nut on the transfer box(behind the propshaft) tight?
Do the hardest job.. A frame bushes & knuckle(replace the whole knuckle with carrier & new bolts) I used the proper bushes for this job as they are a pain to do if they go again.
Make up your own brake pipes or buy the set for your car.
Can of black paint & wire brush to make stuff look nice if...
Well that’s 6 weeks to get the other list of parts needed. & the other 1 stripped.
You don’t want to be finding you need parts & have to wait during the build.
Happy spannering then. It does make a difference for a few years not having to worry about things with a rebuilt motor.
I put the chassis under mine about 1995 as the chassis was shot when I bought it.
Now has a galv bulkhead.
So for welding & make your life easier
Take rear tub off.
Take doors & bulkhead/wings off
Carry on doing the above & your 1/2 way to a chassis swap.
You know you will be chasing rust on the old chassis.
Have you got space to change the chassis?
Looking for a cheap 110 is looking like a challenge.
Why not do a 90? All the parts forward of the door latches are the same.
If your looking for a series motor look abroad,everything fits in a container & gets delivered
I remeber Mrs wanted a few shots of high driven clays,well I forgot the spare shells that day were 36grms 9’s (used as range finders)
She gave both barrels to the clays and me afterwards.
I chuckled and put some 24g 8 in for the next pair.
There is junk on the bay thats asking stupid (high) money by the time you have sorted missing panels you would never get money back.
As for you link that’s had the desert dust eating away at the doors.
Have you tried to put a white plastic bag over the wipers?
(If I remember crows when the hatch have white feathers when born & until they turn black,crows won’t feed them)
Theory may mean they leave white things alone
That A frame cross member would have been replaced like for like. Even has the 4 holes for a bose unit (sometimes on range roves & early 110 for a self levelling devise) Later models use a tubular type for the rear arms.
There are some nice galv fuel tanks to replace that 1.
Engine mounts…...
