Ok... (drum roll...)
The 27F should fit.
I stuck a piece of 2 x 4 flat under the 94R, so that raised it 1.5". The cables and terminals reach the posts. Barely... but they reach.
The Exide 94R (like our OEM 94R) is 7.5" high and the 27F (Northstar / X2 Power) is 8.75" high, so 1.25" difference. It'll fit height-wise, and there's plenty of room above to clear the hood.
Width : the OEM 94R is 6.875" while the 27F is 6.77". I checked the bottom retainer block and it grabs 3/16" on the 94R's lip, so the 0.1" doesn't matter as far as holding it down, no jerry-rigging necessary I'm sure (it would be super easy to do though).
The cables barely make it up to the posts when the 94R sits 1.5" higher, but they make it. We only have a 1.25" rise with the 27F so I don't see a problem. If it does create a problem for some who try, the cables are secured with plastic clips to the bottom of the battery tray, and I'm sure we can pull a bit more cable upwards if need be...
One last diffrerence : the 27F (Northstar) is 15 lbs heavier than the OEM 94R. The tray looks solid to me and I don't see a problem there either...
I'd say it's a go !
You're the best! I'm ordering right now and plan to pickup/install tomorrow night- I'll take pics when I do!
