I just installed Optima Red Top battery in my brothers 96 Probe GT ,i did some modifications because Optima is little higher than stock battery (i made new tray)
Battery in my Stang is old and have to be replaced , so i was thinkin about Optima Red Top battery , for now i gonna install in stock location (under the hood) and i may move to the truck but not right now and i gonna use just for Stang no fancy 10000 amp speakers box

i would go with the 34/78. you may need to notch out your battery tray a little for it to sit flat (i had to with the 02) but it came with the adapter for the hold down so it all fits in nicely
 
Well this afternoon i was bored so i went in AutoZone and bought 1st one 34/78-OR and one battery wire because one from fuse box was 2" short
I had to cut tray on one side so battery sits flat,i use Puck adapter to hold down bettery ,took me about 20 min to install ,dang whan i crank up it start in no time

Thanks guys

BTW i will post some pics tomorrow
 
Not the best pic Ernan, but you can see a little the black bracket across the top, with the wing nuts holding it down... The wing nuts are attatched to to long bolts that slip through the bottom of the tray.
