Please help with a seat replacement

[horticattleman]

I have followed JJ's lead and gone to surplus center which has a great selection, but I don't know what pattern to get. I measured my existing one at 8 1/2" x 10 1/4" for the bolts. None are close to that.

Any suggection on seat replacement for a 425?

Thanks

Maybe you can re-drill the holes to fit. Did you try TSC..
