So, after reading the last few post I went out to the garage and took a close look at the seat. With the standard mounting bracket I was able to sit on the seat and put enough downward pressure to pull the front of the seat away from the tongue. Also, looking at the 1/2 inch forward movement the new bracket would provide does not really affect the original points of contact. I really do not see this as being a bad fix. What the MoCo did with the 407/408 Dunlaps seemed more problamatic then pushing the seat forward a 1/2 an inch. It is unheard of to reverse the direction of travel only to change again but then again, that was discussed at length on another thread. I'm going with the bracket for now, more to follow once it comes in.
