I am trying to find the answers to a few question prior to calling as I am located in Okinawa, Japan till September. Once we get these questions answered I can call and place the order so the parts will be waiting on me upon my return. 1) I am converting the transfer case, I have decided on useing a TH400/NP205 vice my current setup TH350/NP205. I want to purchase the conversion parts from you and wonder about the adapter that is between the TH350 and the NP205 will it work with the TH400 or will I need a new adapter? If I do need a new adapter do you have one for sale? 2) I currently just installed a set of Rough Country Springs front and rear, they shipped 4" front and 6" rear springs. I will not be running with a hard top so the back is at least 2" higher then the front. Here are my thoughts, can I install your extended 1/2" greaseable shackles and remove the overload leaf from the rear spring pack to get it about level? I dont tow anything heavier then a small ATV trailer. I would also like to install your greaseable suspension bushings for the rest of the suspension as plain Poly is much to harsh. On the rear upper shackle bushings the bolt is turned so the head faces the frame, are your bolts and nuts shallow enough to install so this point is greased too? 3) I also need new Performance Bump Stops. Whith the lift I have should I use the 3" or the 4.5" Bumpstops, I do not want to limit the travel of the suspension prematurely?
