OK folks just a little info if you want it. I just installed speedbleeders on my 77 308 GTB and it took 2 hours green to green to do the job. I would assume that all 308's with ATE calipers use the same speedbleeders if you want to buy them. So the pat number fro the FRONTs is SB8125LL (8mm x 1.25 ) and the part number for the REARs is SB7100 (7mm x 1.0) . This was a simple job and they work good in flushing the system by your self. Just thought you would like to know. Their web site is
www.speedbleeder.com or you can get them on 815 736-6296 Enjoy the ride
