On some research and checking my 2 pins (creech and a modern Stern iron man both have the same joint method). But the joint system may need to be a little bit stronger, as reports state some strength issues at the front lip. Doing a 45 degree may have been a feature at one stage but the new sterns are doing the joint the same as the 90's Ballys. So I don't see a big issue changing, but could do a small test panel to do a test on strength of the joint with the lip thickened up a little more.
