Is Item #9 the only part missing?  Do you need 2 for both sides.  Make a list of parts needed and I will see what I have.

Thanks! At this point I should take the other side off so I can see exactly what I am really missing, someone near me thinks they have some too, along with a seat, which is super awesome!

Will keep you in mind, it's good to know where the parts are as I am just getting started on this one. Thanks!

 

As a side note, I replaced the rear brake hose with the Centric one from Rock Auto, the fitting that goes to the brass distribution block fit perfectly, but the one that goes to the hard line was rather difficult to tighten down, along with that the hex fitting on it was too small to fit in the recess and seemed to be a metric 17mm instead of the SAE fitting on the one that I took off. I went ahead and ordered the Beck Arnley one to see if it was a better match, along with some tubing and fittings in case I stripped the one that's on there. Anyone else here run into the same trouble? I am hoping that the nut is just tapered and seals as it tightens?

I'm talking about the rubber hose that goes from the hard line to the junction block that splits out the rear left and right brake lines. It appears to be SAE on one side and metric on the other. The end that connects to the brake line that comes from the front of the truck is definately not the same size nut as the one I took off.  I'll take some pics this weekend when I get the wheel off again.

This sounds about right. Early ones were SAE thread and later were switched to metric.

 

You can get the correct nut and re-flair the hard line. I had a Dodge Omni and on the brake line from front to back, the rear nut was different thread from the one on the front engine end. Dodge dealer wanted $90 for this line. I just bought a generic brake line that fit the front and used the rear nut that fit the block and re-flaired the line.

620s were metric 320, 520, 521 were SAE.  Contact hosestop here on this forum he knows what you need and makes great quality hoses.

That was quick! They already canceled my order, citing the same reason as the dealer.

 

Every order I've ever placed with them has been canceled as OOS. Seems as though they just pretend to have inventory, take your money, and then when it turns out they don't have it in their 3 tote bins in the back room, they cancel. Pretty inefficient way to run a business. Maybe they make money on unclaimed refunds or something (??)
