Can anyone reccomend a good (comprehensive) shop manual...

[rogus]

For '81 there is the service manual, Fisher manual, a unit repair manual (overhaul), a advance info shop manual. I've got lucky to get them all plus a '76-'81('87 edition) parts catalog.

Don't think I got the advance service manual.

Alldata is also a good source. I used it for years in my shops professionally. Also has service bulletins
