Hiya! I'm a new CRD owner... picked up a 2005 Limited a week ago and it has a bad battery

I've been lurking and decided on a yellow top optima-- picked up the 34 today at 4 wheel parts (right down the street from me, didn't know I was so lucky!) and brought it home... but it won't fit. Specifically the red bracket fits across fine, but the black bracket is shaped differently (L-shaped) and won't reach the battery pole. If the black battery pole was closer to the edge of the battery it would work... but yeah, I can't get it.
I know the CRD originally came with the red top 34R (reverse) -- but Optima doesn't make a yellow-R as far as I can tell. I don't know if I need the reverse or if it has anything to do with my problem. Is it just me or is there something I need to do to get the yellow top to fit? I'm not super mechanically inclined-- I use the Jeep mainly for in-town driving and taking my son to school, tho eventually my husband would like to add a winch and attendant lift/etc mods for his weekend use (the reason I bought the yellow top instead of the red).
I may just be missing something obvious to yall on installing it... I can see searching the forums here that the yellow tops have worked for many and I'd love to understand

Thanks in advance for any advice!
