1990 1500 350 Pitman arm

Anyone know how to take the pitman arm off of a 1990 1500? It seems easy but the crossmember is in the way. Anyone have any ideas?

Yeah, remove the gear box for access, of course you need a good puller also.

Have the puller already, so once I remove the gear box I'll be able to pull the pitman arm?

Correct, but a high quality strong puller is required.
