Thanks Jack for the clarification. I do have the 14X14 openings. Also, thanks for the info on the belt for the smaller pulley. Maybe I'll change that pulley as well seeing how I have it all apart. Had a great talk today with Gumpy who is the resident expert at rebuilding cooling system in MCI's. Tomorrow will be a big day becuase I'll get some info and prices from General radiator and Diesel radiator. I am hoping that their prices are reasonable. Spending almost 2k to fix the smaller radiators doesn't seem like a reasonable option to me when there is mounting evidence that suggests they still won't get me over Eisenhower pass.
My plan is to get the larger radiators and replace all the seals in the back and use expanding foam as well to make it as airtight as possible, I already purchased a new air filter from Luke as well new blower scroll seals. A new pulley and seals for the blower gearbox and an aux Hayden transmission cooler and Colorado here we come!!!
I might be in 1rst gear but Eisenhower is gonna be in my rear view mirror eventually.
Now watch, I'll probably lose my Detroit on Vail pass just because I got so sure of myself!!!
Can you imagine the grief I would get from all of you!!!
Thanks again for all your help folks...
