from what I have read on here most of the guys are runnin the 99+ upper hoses and the lowers hose with a little trimming done on the lower hose

I used the hoses that were on the 2006 engine, upper fit perfect, and I had to trim a little off the lower hose. The radiator in my 85 is dimensionally the same as the one in my 68 and 70.

Good deal! I thought I read that same info somewhere, but I could not find it again.

Thank you.

I dont know the 70 radiator but the stock v8 rad in my 65 wasn't working with the 02 stock hoses because the radiator has like 1.75" connections and the LS has 1.4". I could be off on my guess-timation's of the hose connections but not much.

I used the 99+ upper and lower and my truck originally has a/c. The upper and lower hoses were a PITA to get to stretch on the radiator. Must be that the a/c rad. is a larger diameter. Anyone know the diameter of a a/c versus non a/c rad?
