Well, this project has not seen a lot of love the last month or two. I have been busy with the normal job (pays for my life) as well as getting my shop in order and working on another clients Patrols.
Nissan made ALOT and I mean a lot of changes to these trucks during the 1960's. Pretty major change years during the 60's were 1966 and 1968. All of your pre-1966 Patrols are pretty specific to these years. I won't list all the changes here because I doubt they are of interest to readers of this thread but one of the major changes was in 1966 Nissan started wrapping the wiring harness in black. Before this it was wrapped in gray. Took me a little while to find some gray electrical tape but I found some on Ebay and it is in route.
I have the rear wiring harness stripped and when the gray tape shows up I will re-wrap the harness. The original harness from the 64 is a bit worked over and not in the best condition. So I am using one from a 1965 in much better shape. I need to get the rear harness restored and on the chassis before the truck goes back to the body shop.
Many years ago, on my first Patrol, I had a strange issue. A wobble in the front end at any speed over 20mph. At the time I purchased new tie rods & drag link + pitman arm, new leaf spring shackles and a few other bits to try and fix it. Nothing worked. Then we discovered that the spindle was bent. So I found a used one, installed it and the problem was fixed. Many years later (and many Patrols later) I think I have figured out that a bent spindle is not so uncommon on these old trucks. Perhaps it is the weak link in the front axle or perhaps it is just the part the bends before anything else. Any ways, pint is, I discovered on the 64 that I have installed a bent spindle when the axle rebuild took place. Now I have a bunch of 2nd hand spindles here but which are bent and which are not!? Since the bend or damage will always be very minor it is just about impossible to see with the naked eye. So I took 4 spindles to my machinist and had him spin them. He did and two are great condition. The other two had very slight damage to the flange. Odd as I would have thought the bend would be on the shaft. Any ways, I now have 4 good spindles and need to tear out the bad one in the 64 and put one of these good ones in. Little lesson learned, get these suckers checked for true before installing!
The steering box will get rebuilt fairly soon too. The only issues at this point are I need to locate a few o-rings that are large and a bit of an odd size. These are not available anymore anywhere from Nissan so I must try to match them up to something else. I also found some NOS steering box shims for setting up the bearing preloads. Those are in route now. So here before to much longer the steering box should be rebuilt and mounted on the chassis.
The brake lines have been a little bit of a drama too. Original steel lines are wrapped with a fairly thick rubber along most of their lengths for abrasion protection. Now finding new steel lines with this rubber has proved to be impossible. I did find some vacuum hose that fits just about perfect over new steel lines. Going to see if this will work to get the rubber on the lines and make it look as close to stock as I can.
I have been working with a guy who makes rubber parts for old Datsuns. He has taken on the very large project of making all new rubber for the whole truck on the classic Patrol's. I have probably put in over 25hrs in the last 10-days rounding up rubber for him, pulling it from trucks, cleaning it, organizing it, selecting the best samples and packaging plus labeling it all for him. He has already been sent one load but another is headed his way soon which will be the last of the rubber on the truck. Timing wise his new stuff probably won't be ready in time for assembly of the 64. So I will have to use old original rubber I have restored. In the future though I can be using new re-produced rubber on these trucks which is a HUGE step to overcome in restoring these old Patrols.
Not much else to tell. I have got to get the above done in the next month. I am headed to Baja in January for 3-weeks and the 64's chassis needs to be at the body shop by then.
Cheers
