Elf Upgrade & security

Hi

During my Elf rebuild I am trying to remain authentic, with any changes from original to be reversible.

I want the car usable daily, reliable and as safe as poss
if there is anything you can add or take out because its daft let me know.

I was considering

Electronic ignition
Alternator instead of dynamo
Inertial seat belts
Halogen lights
Driving spot lights
Rear fog light


Was going to build a centre console (removable in one)
this to hold a radio and speakers
12v supply & clock

was considering changing suspension to dry type thoughts please!

Alarm?



Also

I'm worried about it being stolen not because of where I live just generally


What would you recommend for protection
Cat 1 alarm? do you need this for insurance?
kill switch?
visual deterrents wheel locks etc?

Thanks for your time!

Regards

Martyn
