help needed - can someone measure some bolts for me?

[digitalpeer]

Gday,

Little help!

My car is currently in a movie set and im unable to get access to it until Wednesday and i have a track day on the 28th. Problem is ive just found out they have made fire extinguishers mandatory!  so instead of rushing around with the 2 days i have between getting my car back and the track day could someone please measure the distance between the front passenger seat mount bolts and what size the bolts are for me? I can then get a bracket made before i get my car back on Wednesday.

I have a fire extinguisher here but i need to get a bracket sorted.

Thanks very much!

Cheers!
