Gm # lookup

[*MJF*]

I have been searching the Gm sites for an hour & 1/2 trying to find a description(more specifically a picture) of the following pullies. Can someone look these #'s up in a GM book?

I need a 2 or 3 groove crank pulley for a 70 350. I found these #'s, but no pic or description other than pulley. I would rather not buy anything else without seeong a pic since I've already bought a pulley & a ps pump that won't work for me.

Thanks for your help.

Mike

EDIT: I guess this is a good reason to preview your posts. I forgot to put the #'s. They are 3744043 & 3751232.

Thanks
