First-time replacing a clutch

[bluesfella]

So, this is my first time replacing a clutch, and I have a question. I have a '66 C10 with the straight 6 and three speed. All original with only 75,000 miles, but rusty as can be.

Anyway, the clutch is out, so I bought a stock replacement. I just pulled the trans out tonight, but I left the bell housing in place. I haven't pulled the clutch off yet, but will get to that tomorrow night. My question - since the bell housing has the mounts that basically support the rear of the engine, I think it would be easier to leave it in place. Can I pull the clutch and put in the new clutch without removing the bell housing? It looks like it might work, but before I get too far, I wanted to ask the experts! Thanks!
