im about to get my 1.9TD engine rebuilt and I would like to get the TDI pulley modification done. Hoever, I would rather have someone who has done it before to do it for me rather then try to explain to my machine shop what needs to be done. If you guys could direct me to the right person that would be awesome.However, if the modification is fairly simple that I could accurately describe it to my machine shop that would be good to as I wouldn't have to disassemble the bottom end in order to send the crankshaft somewhere. Thanks.
