I am in the process of getting an exhaust brake for my '92. I have to replace the exhaust springs with #60 springs. How is this done? Can I put each piston to tdc and replace the valve spring without it falling into the cylinder and being lost? Can anyone give me a part number or where I can get a valve spring compressor for the job. Any suggestions as how to do the job or tricks of the trade?

Thanks for the help
