Alloy side pods on a 410 R

[dibble34]

Hi all

I wanted to try the alloy side pods on my r as I see some team drivers have still been using them. Thing is the ally side pods haven't got the bits on to hold the battery in place like the plastic ones do. So to do it properly I would need to buy Td310155 alloy centre holder and td320005 battery holder bar. Has anyone else converted there's and found a way of keeping the lipos in place without buying the above bits?

Cheers

Dave
