Rebuilt my transom, need help on bracket angle!!!

I have a 1988 V-20 Fisherman and it had a bad transom and about 4 feet of the stringers. All is fixed now and me and my buddy are looking for a transom bracket or plans to make one. I need the degree of angle that the transom tilts back on a OMC SEADRIVE type installation. I will also need the height that a mercury motor needs to mounted at if it is a 25 inch shaft motor? If you will send answers to [email protected] thanks, Jason B.
