I don't miss the fun of old car electrics at all, but it is cool when you are driving around at that age.
I used to like the fact that in my HQ I could literally lay on my back, across the floor pan, in front of the front seat when installing wiring for stereo, driving lights, etc.
Now, to get your head under the dash, you end up suspended like a bat, lying inverted on the reclined bucket seat. Or else in some horrible position breaking your back over the door sill.
My old 1975 manufactured DJ5 jeep was even easier - sliding doors with no sills and a flat floor with virtually no trans tunnel.
There was enough space behind the flat steel dash that I could sit on the floor with head and shoulders in there ripping out the dodgy ex US Postal Service wiring!
mine started out like this one below, but the mirrors, smog pump and all its associated pipework, cat + exhaust, roof vent, sump heater, miles of chewed up wiring and bracketry for radios and mail trays all "fell off".
Rusty bits removed, back lower edge of doors were radiused to match the rear wheel arch, repainted, better radiator, simplified exhaust, hatch in roof for kid with spotlight..
I could lock the doors back and legally drive with them open - or take them off altogether.

Mine, as soon as I finished bolting the door handles and seats back, in it was off to get rego'ed
