Fitting new batteries in old trays?

[Patrick]

How far off fitting are they? Some of my packs have been tight, but if you put them in on the right angle and forced them just a little bit (I found it best to force them towards the outside of the car) they would fit.
Which way don't they fit, length ways, width or both?

It shouldn't be, but just check one of the motor wires that clips on the side of the transmission isn't hanging down into the battery tray, that happened to me sometimes.

I don't really have any advice for modifying anything though, since I've never had to.
