I'm in the process of installing a '93CTD into my '89 Ford. I plan to install Bosch 185 injectors. A friend of mine has the local diesel shop and wants to get them for me. The problem is, he says they are 180 injectors. I have herd of both, but never a comparison. Is there a differance? If so, could someone give me a part# for the 185's for him to order the correct ones. Thanks in advance...
