Don't know what forum this goes in but seeing as I'm building a BEC I'll stick it here.

Where can I get a plug or bolt of the above size. Need to fill a space on the rad.

Is it the thermostatic rad switch hole? Fill it with a thermostatic rad switch.

If it is the sender hole on a polo rad then I know Andy Bates has them

I don't need a sender or a switch. I just need something to plug it up.
I don't see the point of spending a few quid on something I don't need to do the job of something that maybe costs pennies.
If I have to I can use an adaptor with a 1/8 NPT thread in it and fit my water temp sender to it. So where would I find an adaptor. Burton and Think Auto don't show anything on their website but they might have something I suppose.

When I said Andy Bates has them, I was referring to plugs, to plug up the hole.

I'm sure for a few pennies he'll sell you one.

Cheers, I'll give that a try.
