Header angle and cross member?

[BIG DADDYS 84]

installed small block in 84 c-10 short bed stepside ,wanted to run header mufflers straight 4" type. 1st problem headers,seems to angle a bit downward 2nd thing is trans cross member on drivers side will not clear. have th350,and the original single exhaust came up over crossmember on drivers side. will an earlier cross member solve this? and is anyone using header buddies? seams to be a ball socket type of collector that might solve angle problem.thanks
