Battery Tray Bolt Size?

[mnetwork]

I finally got around to getting the battery tray out of my Cobra. It bought the car a few years ago and just realized the other day it didn't have a tie down. The tie down bolt was rusted and broken and no one ever bothered to change it. Just ordered a new OEM tray and tie down wedge, but I will also need to replace the bolt that bolts the tray to the frame rail. Does anyone know the size of this?

I believe they are M5's if I remember correctly.

How about pitch and length?

M5 is only fine thread. As for length, just measure.

I took mine to the hardware store and matched it up in the aisle on their pegboard.

Yeah, I'll head over to Lowes today or tomorrow and report back.

So, I wound up not even needing a bolt. I purchased an OEM tray, but a Dorman hold down kit (http://www.dormanproducts.com/itemdetail.aspx?ProductID=942&SEName=00588). The kit comes with two bolts, an extended one and a shorter one (which these use stock). I liked the longer one (black) for easier access and the shorter (gold) one wound up being the perfect bolt for bolting the tray to the frame rail. Good info for anyone going through this. Slathered the bolts in red bearing grease, so hopefully that protects it from future corrosion. All good now.

Here is another hardware replacement kit if your tray isn't bolted down correctly to the frame.

I decided not to buy that because multiple reviews said the long bolt (the only one I needed) was too short. Also, it is a little pricey for what it is.

Thanks for the link, just grabbed a new one. Mine was a little worn.

I recommend drilling a hole or two in the tray to avoid water pooling when you clean the car etc.

Good idea. I think I'll drill a hole on either side of the main bolt.
