xtra 12 swap

I have a 96 Polaris supersport 440 that I picked up last month. im almost done rebuilding the xtra 10 that's in it now. my question is does anyone have the measurements to install the 121" xtra 12 in. ive tried google search and came p with nothing. the sled is for my wife to just put around on. I already have the xtra 12 skid and didn't realize when I bought it that it is a very disliked skid. but I have it anyways and would like to install it probably in the spring time. ill get pics up of my sleds once I get the Polaris back together
