MY manual is a CD I bought off eBay and it's hard to use. I'll buy a better one I guess. I believe the previous owner was neglectful and that is why I only paid $450 for the car-- no rust and a fairly straight body. I used the cam tower procedure to check for chain stretch but I understand that may not be very accurate. I have dial indicators but I can't follow the instructions for this method on the site. Anyway, using the cam tower, the chain is stretched 3-4 degrees. I guess I just want to get some use out of my pressure unit that I've had for a few years; it is the most precise instrument on the market. I think it's good to keep the brain stimulated. I will get the fitting and try the drip method though. If someone can better explain the proper way to measure chain stretch, I would appreciate it.
