Craftsman 113.29920 10" Table - Saw Dado Insert Length Accuracy/Rounding

[Placeholder17]

Hello all,
I am looking to pick up a dado insert for the named saw (1950's Model 100 tilting arbor saw). Old and new inserts abound on Amazon and Ebay, and all listings give the length as 14 3/8", but my original insert length is 14 5/16".

I am not sure if the listings are simply rounding or if the slot length increased by 1/16 over the decades. Can anyone tell me from experience if they have ordered a 14 3/8" Craftsman-branded insert from Ebay and it fit, or if the 14 3/8" zero-clearance advertisements from say Leecraft fit?

Thanks.

I have a 113.xxxxx and the inserts measure 14". I ordered these in 14". https://www.ebay.com/itm/124483184689
My original insert measured 14".
If the 14-3/8 are 1/16 too long it shouldn't be too hard to sand down.

You can make one with MDF and a piloted router bit if nothing fits right.
