TR3 oil cooler part 2

[tr3bob@aol.com]

Hi listers,
 
I'm looking for some help in getting an oil cooler installed in this rebuild. 
I'm not buying a kit because I already have an adaptor and a cooler. 
 
The cooler is used and some say I should chuck it and get a new one. I went 
through great pains to clean it out and it flushes clean.
 
Has anyone done this before? Is there anything I'll get hung up on? What about 
hose length? 
 
Bob
