Is to wait for two weeks for the parts to arrive, just to find out they don't fit.
I removed the old windshield washer pump, removed the old metal four lobe cam, no problems.

"Install new cam"

Except it doesn't fit. The hole in the cam where the shaft is to be inserted is too small. It's a plastic cam, but there is no way I'm able to install it. So either I have to enlarge the hole somehow, or I can get the old cam adjusted. I need to grind off part of the shaft so it doesn't stick as far out. The lobes look fairly alike, so this is probably the best option.

Now for something really stupid. I can't work out how to install the battery tray clamp. Is it made for a spesific type of battery, or is it supposed to fit all types?

The picture shows the clamp with the correct side up?

The battery is placed on top of the tray, and the clamp mounts how? Is it there to hold the battery in place, or to hold the tray in place?

Half bottle of wine later, and still I don't understand it!

The plastic lobe is all that is available, I guess you need to modify it.

The batt clamp mounts upside down from the way it looks like it would fit :)

Place the battery on the battery tray, the clamp bolts to the protruding part of the tray....Make sure that the edge of the clamp makes contact with the lower protruding edge of the battery.....The clamp secures the battery in place....It doesn't take a rocket scientist to figure it out as long as you're sober!

Except when I put the clamp upside down (which is the correct side up), the bolt that came with the clamp is too short to enter the hole. Well, at least I know which way is up!

Still think modifying the metal cam is the best option. Trying to enlarge a small hole in a piece of plastic doesn't seem like a good idea.

You might also want to make sure that the 'star' gear fits through the opening in the washer pump housing. The replacement pumps have a different size opening than the original pump housings.

I went through the same thing with the washer pump.

Don't hack anything up yet, there's a secret!

The valves and rubber stuff inside the pump is what goes bad.

Use the parts from the new pump to fix the old one!!
It worked for me.

I just went thru this. I ordered a reproduction lower door hinge from our sponsor and my body shop guy could not get the door to fit with it installed. He put the old hinge back on and I may just replace the hinge pin and bushing on the old one.

I ended up enlarging the hole in the plastic cam with a Dermel type tool. The pump installed OK, and now the windshield washer workes as it should. Initially only one nozzle worked, but all I had to do was to blow some air (with my mouth) through the other one, then it cleared and worked without problems.

Found a longer bolt for the battery clamp, so now the battery is properly secured. Why the XXXX would they include a bolt that is too short?

Molded trunk mat installed. Trunk looks very nice now.

Rear seat belts, pitman arm replacement and front brakes next.

It is not a good situation. The inexpensive parts that you now buy, are cheap reproductions of the originals. The manufactures of these parts, have to make them quickly and as inexpensively as possible. Many new parts that you purchase have to be tweaked or modified, as they are not made by the original specs of GM.

For example: A simple shaft is 3 inches long and 1/4 (.250) in diameter. The tolerance that GM followed was + or - .010. That means the 3" shaft can be 3.010" or 2.990" long and it could be .240 - .260 in diameter.

Now someone is reproducing that shaft. They measure it and it is 3.008 long and .255 in diameter. in some cars it was 2.990 and .240 in diameter. The shaft is now made at 3.008" + or - .020 so it will fit all cars. This is doubled every time the part fits another.

What you get is a sloppy fit or a part that doesn't fit at all.

Always use the original parts or GM replacement parts to guarantee (not always) the correct fit.

After awhile a parts changer turns into a good fabricator !

What he said. It works.
