Well, I think I've solved my cooling problem! /forums/images/graemlins/grin.gif I replaced the old Hayden fin/tube cooler (have no idea how long it was on there) w/ a new Hayden stack plate from PepGirls, kit# 679, 3/4" x 11 3/8" x 11". The new stack plate was about 25% bigger in surface area than the old fin/tube. I have been running at around 200 - 210 degrees w/ the old fin/tube. Took her out today w/ the new gear...never even touched 175! /forums/images/graemlins/thumb.gif The air temp today was 5-10 degrees cooler but I conservatively estimate I got 20 degrees out of the new cooler. Just extended the life of my transmission and am loving it! /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif It's also a big relief b/c I thought I screwed myself running 33s on 3.08s. Oh, here's a pic of my install. Used the center member of the front clip to mount one side and then used a bracket to get the other side.
