Grainger valve part number

[buick1987gn]

Can someone please post the part number and directions to install the grainger valve on a car ( I have the mcmaster part # but there is a grainger ten minutes away) I've heard that there is some drilling involved so any clarification would be great . I did a search but there was nothing that came up. Thanks in advance

Hope Bryan doesn't mind me coping this

"man you crack me up--
keep the stock wastegate- dont even touch it, go to Graingers and buy this part-
4A788A
its a parker bleeder valve- all you do, is disconnect the black hose that leads to the wastegate solenoid on the pass side valve cover, and put it inplace of it-
this will give you total controll of boost, and you dont have to get your hand hot by adjusting your wastegate rod!!!
the vavle is 13.00 and dont for get the 1/8 male hose barb to make it work-
yes the valve has a inline check valve for controlled boost-

that's not a good grainger part number according to their web site. Ive seen that, but other posts have said to switch what side the check ball is in, relative to the spring and to drill out the end of the 1/8 male hose barb. or is it really plug and go play
