1985 300D - rhythmic thumping sound near transmission ??

There is a rhythmic thumping/knocking sound coming, I believe, from the area of the transmission. It is really audible inside the car, less so when outside or under the car. In the car it is difficult to pinpoint as it seems to move around depending on where my head is at, however I'm pretty sure it is strongest around the transmission hump in the car.

Here are a few other details:

* The noise seems worst/loudest in the morning.

* Doesn't seem to affect driving of the car.

Mixing injector cores when rebuilding?

I need to rebuild the injectors on my 1979 300TD, and I have a set of Monarks that I ordered here. I have access to a pop-tester and a shim kit.

I asked my mechanic about obtaining cores so I could do the rebuild at my leisure. He sold me ($50) a mixed set of turbo and non-turbo injectors, after measuring them and deciding it would work.

I don't think he's correct. I suspect the springs in the turbo injector bodies are stronger, and that no amount of shim removal is going to get me the required pop pressure.

Can you confirm or deny?

thanks!!
