Update: Well, I visited a new friend last night, Terry C. of Coos Bay, a real champ who upon first meeting me jumped in to help me out with my rear gate problem. But this story is both happy and sad as you shall soon read: Sorry for the poor quality of the photos I only had my phone camera with me...

First we used his torch to heat up the hinges to get anywhere with moving the frozen pins.

Then we pounded Sad on the hinges to move them out.

This one here was a real stubborn bastard; ultimately requiring a tack weld on the hinge bracket to keep it from moving. All the other hinges pretty much moved after a minute or two of the torch.

We used wet rags around the bed and body to try to protect the paint and bed liner as much as possible. For the most part this worked well.

Finally we got the worst of the gates off and started to tackle the repair.

Terry being a much better welder than I tack welded the original broken piece back on and then we did our best to align the hinge. This required a bunch of gate placing and testing on the bed.

And here are the final results (again sorry for the pic quality); as you can see the top pic is of the hinge which completely broke, the bottom was the severely stressed one. Terry was able to weld, grind, and sand the top piece pretty much to stock shape. The bottom one actually looks better than the pic shows. For the pins I took them all to the grinder and wire wheel to get the crust off, added a liberal amount of grease on them and was able to replace them all back on the truck. As a result of the work there are now a few paint chips missing from the hardest worked areas; however we have a solid repair that now looks as bout as stock as you can get. The red primer that you see is a very TEMPORARY seal until I can get in there to strip, treat and properly prime. Needless to say I will be facing a paint job sooner than I expected.

Now the sad news, during the work I had removed the rubber VW items that fit within each gate hinge and placed tham in my tool bag; see:

As I was doing this I remarked to Terry: "Gee, I need to write down this part number incase I ever need to replace." Terry and I did all of this last night right up to sundown. I went home, left my tool bag in the back cab and forgot to lock my door. Surprise! Crying or Very sad This morning I found my door half open and my tool bag, rubber parts, spare license plate, CDs, and my DoKa car journal gone!!!

Fuck I hate tweakers!!!!!!!!!!! Evil or Very Mad Evil or Very Mad

So my question to all my DoKa friends is what is the part number for those rubber inserts in your gates; and does anyone know where I can find them?

Thanks.
Bryan

Thanks,
Bryan

This won't answer the recent questions, but this will deal with the contigencies I have with Doka gate.

First of all, I had an accident 3 years ago where the hinge and pin were torn off.

I was able to get the NOS hinge from a European based supplier (will post part no. later):
http://www.ibexparts.com/eng/spare_parts_urgent_delivery.asp
Shipping is only 2 day or something like that, so you will pay through the nose, but sometimes this guy is the only option. He has come up with NOS parts that almost no one else has.

Anyway, I got the hinge and tristar eric welded it on for me (thanks so much!). I have a small lathe at home and machined a brass rod to size to act at the pin. I threaded the pin ends and used button head allen bolts with fender washers to retain the pin.

The brass pin eliminates the steel on steel contact, just have to keep it lubricated. The setup also looks much better than the VW kluge setup. Eventually if I can get the other frozen pins out, I will put in brass pins there as well.

The second contigency is to buy extra gates when you find them. I have a rear and a side for spares. I have been off list for a while, so I am sorry that I didn't see this post sooner, as I could of offered them.

It seems you did the right thing though as it is almost always possible to repair the gates rather than switch them out.

Believe this is the hinge part no.:
Hinge 707 829 361 Euros 60,03
Today it costs a fortune, I think I will start investing in pesos instead of US$, lolz.... Wink

Thanks Keith,

But what are you refering to about the hinge? Do you mean the hinge bracket that is welded to the truck bed body or are you refering to the hinge sleve that you would weld onto the gate "hinge stud" and slide the pin in? Pictures? If your truck is handy can you get me that rubber part number stuffed in the hinge stud; I know it starts as 245?

Thanks,
Bryan

Thanks TurboTransporter, I also got the pin number as: N90054902 from Syncrodoka. Ken at Van-Again says he can pick up each (stop buffer) for me at $7.20 and $10 respectively.

Cool. I just saw the other thread. Funny that the two very differnt parts are given the same name... translation perhaps?

I started washing the rubber gate inserts with 50/50 Simple Green so I could read the part number and the dang thing started to melt!

I wonder if Ms. TurboTransporter would let me put them in the dishwasher? Laughing

hinge 707 829 361 is the vertical bars that are welded to the dropgates that he is working on in this pic.

Correct. I think when I had the accident the hinge that attaches to the body was still close to its shape, so it was reused. To make one you only need high school shop skills anyway.

Sorry for moving tangent to the subject but has anyone found a source for the Tristar alloy gate hinges? I'm planning on getting them CNC milled but sure would prefer to get them ready made. I can't remember if it was Russell, Stuart, or CJ who had some made in the UK. Unfortunately, they only made enough for their project. The orginals were extruded but copies will likely be cheaper to produce as a machined part.

Here's my trashed hinge:

are the drawings for these floating around?
