What is the piece called the holds the battery into the plastic case? I am in need of it, but knowing what to ask for appears to leave me at a loss. I fabricated something for my old battery, but the new one is a little bit bigger so I would rather just get the stock piece.

 

battery tie down (the piece that goes over the top)
and the J bolts that clamp into it and go into he battery tray.

no affiliation with the website, just providing pictures to make sure I'm clarifying the right thing

On a related note:

Does anyone have a link to a generic decent battery tray/hold down that they have used in the past on these cars? My stock one is basically unusable, and I am looking for something safe to use until I relocate the battery.

 

make a sheemetal battery tray, paint it, and then zip tie the heck out of it if it is going to be temp. I had mine ziptied to the radiator bracket, a bolt hole behind the headlight, and a few other spots I could find, all connected to a ziptie "belt" around/over the battery. I could put all of my weight on it in any direction and not budge it, looked goofy though.. back to the factory battery tray now.

sub 10 dollar fix. battery tray's are expesive if they're just for temp.

 

Well I have my zip tied all over, and it looks embarrassingly ghetto. There are alot of $20 generic battery trays, too many actually, and that's my problem. I am being OCD and can't pick one. I guess I just need to bite the bullet.

 

I have the tray, looks like I just need the tie down and j bolts, thanks for the assist.

 

J-bolts and a tie down are available at most auto parts stores and I've even seen them in Wal*Mart. They should run you only like $15

J-Hooks at Wal*Mart.. Can't find the holder.
