You did a wonderful job, This is a great 620 custom. P.S. I did a disk break conversion on my 1974 620 with honda rotors and hardbody calipers with a 280z master cylinder. With the stock a frames.

What's the tire size on the Q56's?  The Pathfinder's total diameter added up to about 24.4".  How much lower in the front and rear are you from stock?


those are Pirelli P-Zeros 225/40/18 wrapped around the QX56 infiniti's. my friend lowered the rear with 3" blocks and de-arched the leafs 2.75" for a total of just under a 6" drop. afterwards he lowered the front to level the truck evenly. currently my '74 is lowered 4.5" using 2" blocks and sits level measuring 24" from the center of the wheelwell arch to the concrete floor. when i used 3" blocks i would bottom out and the rear axle would hit my cut-down rubber snubbers. i may end up c-notching the frame if i decide to go back to 3" blocks. oh BTW, my friend's truck always bottoms out.


here's pics of the infiniti's centercaps. the owner installed 4wd fenders and bed to get the wheels to tuck inside. hardbody's has a wider track width than 620s and 720s.

How bad is the ride when a 620 is riding on the pump stops? Can you still drive for long trips? I ask as the front of my 620 sits high sow I would like to even her front to rear.

from my experience, if u lower it with 3" blocks without doing anything to the leafsprings and  leveling the front then it shouldn't ride on the bump stops at all and you'll be able to drive long trips without a problem unless u have bad shocks. u might have some tire rub issues with the 20s though, may happen when taking turns.

I've always contemplated a c-notch setup that would have removable panels in the bed so that you can have a functional bed at normal ride height and then take them out when you are cruising...

I really envy the motivation, time and craftsmanship that you put into your projects!  What do you do for a living, if you don't mind me asking?

That roof looks great!

Ezcruiser, It would be cool to make your panels work on a cantaliver set up so they moved when the truck got lowered.
