You have any recommendations on where we can find bolts that match the specs you listed? I'm going to call local machine shop last resort.I discovered that the previous mechanic had all of my hub screws loose. I realize that Toyota didn't spec torque for Warn hubs. But, it was as if the axle grease wasn't able to get out of the way of the thread, and it didn't torque for bolt stretch, but, it torqued for compressing grease. Either way, I'd really feel sketchy about 300-series stainless hardware. This is a critical drivetrain component. Steel outperforms stainless steel in so many ways. Like it doesn't work-harden, so you'll have a better chance drilling-out if you do have a broken screw. Plus, it has an ultimate yield strength greater than stainless. The numbers for the 'class' of Toyota screws were 7, as stamped on the heads of my '75 with Warn hubs.

The bolts holding the hubs on should be hex head so the locking tabs can be used. There is really no need for 10.9 grade hardware.
Yeah they are 13. I am just going by what I found on it. Cruiser Corps and Outfitters don't carry the bolt kits from what I have seen. Looks like it's going to have to be DIY. I found some 8.8 as you recommended and ordered those. I'm going to have to get some of these "wave" washers also. I packed that hub full of grease and it was coming out the bolt holes as mentioned earlier. I'm glad you guys mentioned the density rating on these for sure. It's a big precaution safety wise and easier on the pockets.Those are too strong. The aluminum hub isn't up for those stonger steel (10.9) fasteners. 8.8 is available at Hillman, at the ACE or whatever, likely in that length. In theory, screws are tension springs, keeping parts from disassembly. That means that lower 'Class' or 'Grade' hardware needs less torque to make the shank of the screw stretch, and keep the parts from disassembling during service. When you go up in 'Class' / 'Grade' you need to also increase the torque applied to the screw or bolt to have the same amount of spring-load from the screw or bolt, which is a problem, because it might exceed what the Warn aluminum hub can handle. The higher 'Class' and 'Grade' fasteners are often heat treated, and made from a medium carbon steel - they don't stretch much and can be subject to loosening.
Toyota screws would be ideal. They use with a captive lock washer, in this application, if you are looking for OEM-hardware. If not, use a 'wave' washer so it doesn't gall the aluminum hub. The original factory hardware was 12mm on the head, not 13mm. I'm not sure that it matters, but, you might check for clearance...
@Pighead, or anyone else, do you have any pics on the hose setup to bypass the vacuum valve? I see why you were recommending this in the first place now. I have plugged the larger part as you recommended.Just plug the big one if you're not running a smog pump.
The little one goes to your valve cover
Got a whole set of these from CruiserTeq. Correct and look great.You have any recommendations on where we can find bolts that match the specs you listed? I'm going to call local machine shop last resort.
Needing some advice before running wires to new tail lights. The old wiring is currently run through the frame which is filled with dried clay. I'm just wanting to get it running for now. Do yall see any problems with running the wiring around the floorboard to the back on each side and drilling a hole through the backpan and running wires through that?
