I have inherited a Lawn Boy Gold Series Model 10545 with a 4.5hp commercial grade engine (1994 by Ser No.). It had struck an object which left a dent in the blade, and the force of it broke the engine mounting/muffler plate. The mower appears to be in very good condition, and I would like to resurrect it. A new plate is quite expensive, and I cannot find an exact used replacement (pn: 92-1054). Do any of you know of another mounting plate that could be substituted? Would appreciate any info on this that any of you may have. I did look in the lists for something on this, but did not find anything. Thanks.
