I had been waiting for along time for Gerry to get me a batter tray. It finally arrived and I was able to install. I needed to bend the legs a little to get it to fit. It was awkward drilling the holes through the footwell and wheel arch but managed it eventually. Whether I actually have it level or not is another questions, I guess I won’t really know until I have the right wheels!

Did you bolt or rivet it? I was going to bolt mine – due to fix it in place this week…
I bolted mine too. I had trouble working out what level was though, not so straightforward on a slopping floor and the way the cobra sits.
