In the never ending quest to make my van a safer, more reliable, dependable and comfortable vehicule, I'd like to have your thoughts on the top ten improvements you've done or are going to do to your van.
Thanks to help from Donivan, I've installed a fusible link on my wiring harness....big safety item we should all have. More items on my list are elec ignition, gen2 mater cylinder, disc brakes, a timed fan, throttle cable, sway bar, motor box insulation, weather stripping, alternator, new fuse panel, oil/temp/battery gauges, and the list goes on.
So, share your thoughts, your changes you've made, and lets make our vans safer and more dependable than they were 40 some years ago when they were manufactured.

great start on the list . heres a couple more things, up graded lighting (leds) , convert to TBI system .power steering and brakes, GPS,

For most of us, it's a task just to get it back to where they were!!!
I find that fire and crashes are the top of the "TO AVOID" list, so I'd start with upgrades to wiring and brakes.
Depending on how the van is to be used, suspension would be next. This would include any upgrades to the wheel/tire package.
Even in good stock condition, these weren't sealed very well. Make sure you are not pulling fumes inside!
After that, make sure you can see and be seen with good lighting and a charging system that can power them.

This assumes that the fuel system, wiring, and gaskets to prevent leaks are all in good shape. Also, nothing is going to fall off or break. Like I said, getting them back to OE is the first and toughest part of the plan.

for me Disc brakes , improved cooling so far

Seat belts

Thats a big list ,, about the only things I havent changed on mine is the skin and dash wiring, which I need to take another look at seeing as I found a couple wires with the insulation cut back today while tracing some others,( either overlooked or forgotten) probably forgotten ,,lol

Insulation, Mileage & towing improvements, Ease of driveability for each owner,
sound improvements /GPS,, Reliability of ALL mechanical issues, Paint for each owners individuality & needs.

Great points above,y'all. One of my "Oh,yeah...." things is...dont forget to check out the rears(on the vans).Lotta of us remember the front brakes & upgrades that include bearings.Dont exclude rear bearings & u-joints.Could make for a real bad day.

door staying locked so they don,t pop open if some one leanes on it.i rember like yesterday my dad allways telling us kids do not trust the doors never lean on them or push on them they sometimes did pop open. i will be looking into that when i hang my doors. Bear
