TTI manifolds-back 2.5" kit, questions

In the process of installing the TTI exhaust kit on my 65 valiant, 318 and 4 speed. Note that i'm using the orig 273 manifolds, eventually may get the headers. Anyway, i have three questions for those of you who may have done this:
1) oil filter access looks very tight. Did you use a 90 deg adapter? How did you orient the filter/adapter? how hard is it to change the filter?
2) how did you re-route the parking brake cables?
3) the tailpipes hit the rear valance. Not sure how to mount the supplied hanger brackets, the instructions don't provide details.

Any pics would be very useful! Thanks in advance!
