Is There A Special Socket Wrench To Pull Injectors? Case 1835 C

[jdubya]

I have a Case 1835C Uniloader with the TMD-20 3cyl Diesel engine. My socket is too thick to fit down around the injector. Is there a special thin wall socket to pull injectors? Thanks, Jdubya

Some times you need to remove the rocker cover to get the socket around the injector, is that what it's hitting? If not, can you get a cheap deep socket and machine the wall of it down to make it fit?
I know i have had to do this with spanners to get them to fit, cut parts off to get them in tight spaces.
