Having owned a 62 I can tell you these little tidbits from my experience;
1) With the gas engine mileage really sucks. not kidding, its bad.
2) With the auto transmission its the slowest vehicle I've ever owned. ever.
3) With the stock suspension the ride is harsh at best.
4) With the quad headlights you get ribbing from coworkers about your "lifted Volvo wagon"
But...
An H55 5 speed conversion solves problems #1 & 2
An Old Man Emu suspension solves issue #3
An FJ60 grill and headlight conversion solves issue #4
My wife loved the truck UNTIL she drove it (she made me take it for the test drive and I told her it ran & shifted well, should be great, but its obscenely slow - she thought I was exagerating until she drove it after we brought it home & realized I had it pegged to the floor to get it going as fast as I did on the test drive). If I had known about the 5 speed conversion we would still have owned the vehicle today. I wouldnt hesitate to buy another but the 5 speed conversion would be a condition, not an option. Here at Iron Pig we do both the 5 speed conversions and OME suspensions on them all the time, and its great to see the amazement on the owners face after they have test driven the truck upon pickup, every one says its like a completely different (for the better) vehicle afterward.
When looking at them in rust prone areas, the normal body rust spots are tail and lift gate in the rear, lower rear quarters and rockers, lower door corners, around the windshield, rain gutters and the leading edger of the hood. Underneath on the frame pay special attention to the double wall/layer section on the inside of the frame rails on either side of the spare tire underneath. Thats the main location they rust out badly because water gets trapped between the 2 layers of steel and things go bad quick in states with salted roads. This is VERY common:
