Will a D34/78 Yellow Top fit without modification??

The dimension differences are:
Length 10" vs 9 5/16"
Width 6 7/8" vs 6 13/16"
Height 7 13/16" vs 7 5/8"

You are talking about a few tenths of an inch at most. It will fit.

If you want the battery to sit flat:

You will need to trim the battery tray.

I believe that's the one i have. I had to cut the lip off the tray. But the battery hold down still works.

yep you ned to cut the front lip off the battery tray. I thinnk it is two bolts holding it in after the battery is out. I used my dremal and made short work of it. You could also use a pair of wire cutters.

Trimmed the battery tray for mine. Not a big deal at all.

So by front side do you mean the side that faces the engine, or the side that faces the front of the car?

And btw, thanks guys.

I think I had to trim both sides to make mine fit (facing front of car and rear)
