Do a leak down test and check the bearings. If all good.. run it. If the motor has a questionable history maybe a rebuild it.

I pulled the bottom end to check the crank and rod bearings and will most likely replace them all. still deciding on whether to pull the head, head gaskets are cheap for this motor (compared to Subarus).





Also finally got the dashboard out and soaked the chassis bolts for the cab. Aiming to have the cab off the frame in the next week or so.

You are really tearing into this truck. I remember when I was at that stage of taking everything apart, it's a lot of fun but you will have more fun when you start putting it back together.

It's been awhile and I have a few updates. The cab is off the frame, the mount points are very damaged, i need ideas on how to repair and reinforce them - doesn't have to be pretty, just functional. 

Floor should be simple, i have some 22 and 18 gauge sheet as well as easy grind welding wire. 

The next question is front suspension, i would like to move away from the torsion bars and do coil-overs.

What about coil overs, most everything i have found is for doing coil overs on the king-pin type front.

I have the ball joint control arms and non-vented disc brakes. What are my options for vented front discs, i don't want to have braking issues with the more powerful motor. 

Not there yet, but i'll be doing rear disc brakes, would like to do a stronger hand brake as well.

Steering component wise - I need new tie rods and joints all around - including the ball joints for the control arms. 

Also considering drop spindles but still undecided.

Beebani makes coil over kits for the ball joint 620"s. But you will need a custom upper a arms which he also sells.  Pics show custom a arm with two inch drop spindles with slotted drilled rotors

I picked up Beebani's coilover kit and adjustable a-arms. They shipped quick and look great! 

I'll do a detailed install as soon as i'm ready, but in the meantime i documented the full disassembly of a front corner.


Too many pictures to paste individually here, so i started a google photo album.


It was more of an archaeological dig than a mechanics endeavour, but it was well worth it.

It's been awhile since i've posted. I've made quite a bit of progress and gathered most of the parts I need. However, i just accepted a job in San Mateo which means we'll be moving by the end of the year. That means I either need to find someone to finish the pickup for me, place it in long term storage, or sell it. I'm leaning towards the first option, but have no idea how to go about finding a trust worthy shop that will do a good job - any suggestions either locally here in Washington or in San Francisco area? 
Here are the latest photos. The engine is ready to be assembled, the torsion bar adjustment brackets have been shaved off, there's a small rust repair needed at the rear of the fuel tank mount, otherwise the frame is ready for Por15.

This is the style i'm going for:
