[QUOTE="Dan_Goodwin, post: 1571014, member: 4960"] I purchased 2 finishing clamps ([URL='https://www.amazon.com/gp/product/B093QZFJLW/?tag=hardlinecrawlers-20']LINK[/URL]) and used the leftover AN hose to plumb the transmission cooler. The transmission has a ¼" NPT fitting that I needed to adapt to AN-6 – Summit Racing had the adapter I needed for this ([URL='https://www.summitracing.com/parts/SUM-220647B']LINK[/URL]). I used 2 45 degree fittings from the kit to come off the transmission and routed the hoses along the driver side frame rail and up to the barbs on the cooler. I'll try to get some pictures of this – it's difficult to photograph once installed. The power steering cooler was plumbed in using hose from the transmission cooler kit. This was as simple as removing the return hose and routing the new hose. The AC condenser was re-installed and then the Summit Racing radiator. And here's where the issues come up. : [LIST] [*]Motor mounts installed in the AA recommended location do allow the use of stock exhaust manifolds. This saves a lot of time and cost being able to re-use stock parts. [*]I have less than 2.5" from the threaded fan mount of the water pump pulley to the condenser - there's not a combination that I've found to be that narrow and I've looked at both electric and mechanical. With a V6 Dakota fan clutch installed, I have 2.5" from it to the condenser, only slightly more room than a stock radiator. Proform advertises a Slim Fit radiator and fan combo that would fit, but there is alarmingly little information and forum chatter about it and its $700.
