Buttoning Up the Little Stuff on my Project Car - L24 1973 240Z

My first project car is a 1973 Datsun 240Z. Like many cars, it was mostly stock with a lot of rust when I bought it around 5 years ago. I taught myself to weld and did all the rust repair. I replaced floorboards, frame rails, and many small patches in the fender wells. Then, I rebuilt the braking system and replaced numerous broken or rusted-out parts. Next, I re-gasketed the engine, drained the fuel tank, and cleaned the fuel system. I took the car down to bare metal and tried a DIY paint job. After that, I drove the car for about 3,000 miles around town and on a couple of road trips. I had my fair share of trouble. I had to replace a fuel pump, the alternator only puts out about 12.5 volts, and the wiring harness is starting to show its age, and the previous owners that created a rat's nest. 

 

Recently, I purchased another project car that came with a lot of parts and swapped them on. I added TTT coilovers all the way around, Arizona Z Car lower control arms front and rear, Arizona Z Car tie rods, upgraded front sway bar, new front valance, fender flares, and trimmed fenders for clearance, Watanabe wheels, and Toyo R888s (215 front and 235 rear.) I also cleaned up the interior a lot with new door cards and interior trim pieces. Recently, I replaced the billet diff mount with a new polyurethane one, fixed a lot of my early welding, did a full engine service, got the door handles working promptly, and modified the exhaust because it hung about four inches too low. After this, I put about another 2,000 miles on the car. All this work has the car in pretty good condition, but there are still a few things left to have a true daily driver quality car: 

 

1.) Fix the exhaust. I got it tucked up nicely, but between my poor welding and previous owners, there are several leaks, and it sounds terrible. 

 

2.) Rewire the car. I have the brake, reverse, and running lights working. However, I have never been able to get the turn signals to work, and the gauges work very seldomly. I have purchased a 21-circuit harness from EZ Wiring and will rewire the whole car in the next month or two. https://www.ezwiring.com/product-page/ez-wiring-21-standard-wiring-harness

 

3.) New gauges. EZ Wiring sells new gauage kits. I'm not sure if the 50-year-old gauges are broken or if the wiring harness is bad. So, I think I'm just going to replace the gauges with a set I know will work with the new harness. https://www.ezwiring.com/product-page/shark-mechanical-gauges

 

4.) Re-attach the skid plate. I had cut the plate off because the bolts were rusted and stuck in the car. I fixed the plate by welding some washers on the bolt holes, but I need to drill out all the old bolts and tap for new ones. I don't have the car lowered that much, so I'm not too concerned about it, but it would be a nice piece of mind. 

 

5.) Alternator. Ever since I have owned the car, the alternator has not worked properly. Recently, I had the alternator rebuilt with quality parts and bench tested. I know it works, but the car is only putting out 12.5 volts when running. I have played with the wiring and got the alternator to put out 14 volts, but then you can smell the wires burning from too much juice. Like I said, there is a rat's nest from the previous owners. I am at least the fourth owner, but I don't have a full history of the car. I have an FSM, but the wiring guide no longer matches because of all the other owner's work. This is why I plan to replace the whole harness. I'm hoping the new harness with better relays with fix my charging issue. 

 

6.) Alignment. After I put the new suspension on, I did a garage alignment, and it is pretty good, but I would like a professional to take a look. I have that scheduled for next week. 

 

7.) New Dashboard. My current dashboard is pretty rough. It has several cracks and looks pretty bad. I have a newer, crackless dashboard. When I rewire the car, I'm hoping to swap the new one in and put some sound deadening behind the dash while I'm at it. 

 

I'll post my progress if anyone is interested, and I'm sure I will have a couple of questions. I know the last finishing touches take the most amount of time. I'll also answer any questions anyone has, but I'll warn you that I'm a hobbyist. My full-time job is as a lawyer, and I'm by no means the best mechanic in the world. My welding has also gotten a lot better, but it surely isn't that good. 

 

Thanks!

This week, I feel like I didn't get nearly as much done is I wanted. I went to a local shop and got an alignment done. I built some low profile ramps to make jacking up the car easier, and it is 100% better. I also gave the car a wash because it was filthy from sitting in the garage for so long. 

 

I also drilled out the rusted bolts from the skid plate. I removed the skid plate a couple years ago to fix an oil leak. All the bolts were rusted, so I cut the heads off the bolts just to get the skid plate off. I regret that now, because it was a pain in the butt to drill out all the bolts. Now, I need to go back and tap the holes for some new hardware. 

 

I also found some more rust. Both sides of the frame rails where the sway bar attach are pretty bad. I don't remember them being this bad when I first did rust repair. I upgraded to a beefier sway bar about 1,000 miles ago. I also have driven the car pretty hard through corners and turn since upgrading the suspension. I wonder if the new bar and hard driving could have brought some rust I missed to the fore front. 

 

I'm not an amazing welder, but I'm also not awful. If I was doing this correctly, I should have removed the sway bar to get more access, but I feel like it's good enough for my standards. 

 

I also started soaking the exhaust bolts/nuts in PB blaster because that has to come off next so I can fix the leak. The goal this week is to: finish the exhaust, install the skid plate, more rust repair, and adjust the front suspension to sit better (it is a little high for me right now.)
