Cadillac: 88 Fleetwood Window Regulator GUIDE intall directions???

Hi all,
I have an 88 Fleetwood D'Elegance FWD and the drivers window regulator
guide needs replaced. The plastic piece that rides on the window
broke.
I bought a new regulator guide at my local Caddy dealer and I
succesfully removed the panel, etc... from the door BUT I cant figure
out how to put the new guide in....
Does anyone know how to tell me how to do this?
Anyone have diagrams, etc...?

Help!!

Thanks for any help!!!!
