maybe someone can help here...looking for a lower blade guard for a delta 10 inch miter saw MS 250...the plastic guard that moves as you pull saw down...bought this saw for 20 bucks and it works great ...it's just that the lower blade guard is missing ..I have used it but I feel a bit safer with the guard in place...I've looked all over the internet and find the part is discontinued...my only hope is someone might have a non working saw they no longer want or possibly some where else on the internet that I missed like a collector or whatever ??...thanks for any help / ideas
