K1 Seat rubber buffer hole size

[r1_pete]

I bought a seat base of eBay, in a heavier gauge than original, but, it was cheap as the rubber buffer holes are too big.

I need to do some welding this weekend so was going to correct them, can anyone tell me what diameter they should be?

Its for the rectangular seat to frame buffers, K1/2 etc.

Cheers.

Pete.

My seats are up in the loft Pete. If someone like James is reading he probably has easier access but if no reply by the weekend I will go up there and measure one for you.
 
Can't believe they paid for a press tool to stamp those seat bases out in steel and cocked up the holes. I know "Bob-the-Seat' in Newent Glos.  sells them and others on eBay do. Wonder if Bob had them repro'd?

Cheers Ash,

I think it was Bob I got it from, it is a really nice pressing and much sturdier than the originals, so I thought it worth a  punt at about £20, I can get the holes welded up with some discs with a pilot hole in and drill them out at a later date.
