I got this at the local Canadian Tire store one or two years ago. This DOES contain Phosphoric Acid. I'm pretty sure they still sell it. It works well, usually takes a couple aplications on badly rusted areas. See picture in link. http://album.hybridz.org/showphoto.php?photo=12617&cat=500

I finally got all my weekend honey-do-dis honey-do-dat list done and was able to spend some quality time with my cylinder head. The front cam tower shims measure at .015 and are a different shape than the others so they can only be used in that location. All other shims measure at .020 and are the same shape. First I stacked all five sets. This result was obvious but I tried it anyway. NO a cam will not turn if one tower is off by .025!! Second I tried stacking five .015 front tower shims for a total of .075 and four .020 shims on all other towers for a total of .080. Leaving me with a difference of .005. Again, NO a cam will not turn with one tower off by .005. (at least not without force) Third I stacked four .015 fornt tower shims and three .020 shims on all other towers for a total of .060 on ALL cam towers. YES the cam turns with great ease. This was all very time consuming but I think it was time well spent. I'm sure there was a mix-up in the packing form Goodson and I will try to contact them in the morning.

I have my douts too that the cam would turn being off by .025! I'll try a mock-up with an old cam and see how it goes but I don't think it is going to work. One option is to mill the head .060, then I would have the correct thickness shims. Unfortunatly I would not have my desired end result.

I recieved my Goodson cam tower shims today and they are not the same thickness. I bought a total of 5 sets for my p79 head (planned on milling it .080). When I measured the thickness of the shims today I discovered that they are not the same. The thickness of the front cam tower shim (the one closest to the timing chain) is .015. however the four other shims measure at .020. I went through all of the shim sets and they all measure the same .015 for the front cam tower and .020 for all others. Has anyone run into this before?

Marc's user name is marcg. I knew he had posted on Hybridz before.

No problem. Actually I'm surprised that he has not been on Hybridz discussing his project.

His name is Marc. I don't know his user name though. He lives in Kingstone Ontario, about 2 hour drive from me. Last time I spoke to him (a couple weeks ago) he was doing wiring for his Q45 swap. I have seen the car and some of the work he has done to it. All I can say is INCREDIBLE!! We are both members of the www.TIZCC.ca Thousand Island Zed Car Club.

Check out Zedfindings www.datsunzparts.ca. He sells floor pans, frame rails and various other items. He is located in Kingstone ON.
