Ill give you a call a little later today and leave you my number as well if I dont get ahold of you. I really wanted to keep the stock kmember, I have read a few guys doing that and still being able to run 3.5" downpipe. 3" clears without even notching the stock kmember and I think what I read in one thread was a guy did a 3.5" setup and just notched the stock kmember a little. If you wanted to run bmr's stuff, that would be cool still too, I can actually get you a little discount on that if you do want it. They just basically sponsored our 2011 5.0 mustang we are getting ready to do and shipping suspension for that today.
I just really would like to do everything possible to keep stock suspension, as far as a selling point, thats huge. So many people dislike the mod motor kits when we mention swapping kmembers.
As far as goals, just like what you mentioned. Maybe a standard 70mm included in a kit and mock up with a 76mm as well to make sure there is room to upgrade down the road. I have drawlings for the alternator relocation I just need to get machined. I didnt do anything yet just as I havent had any need to get it in the work. Ill talk to you more a little later
