Thanks Newton. I've never heard of the "technicians guide". I have Danny
Boone's book and the PACE manual by Bill Spurlock. I'de better call the
home office today.

Some of this may come under warrantry.

I've replaced two sets of action brackets for two differenct companies
under warranty. But they only pay for about 6 hours of work. They feel
that only let-off and drop need adjusting. I've always ended up doing much
more work than that.

Thanks for your input.
