Hi Guys,

Ok, this is probably a dumb question......but I was looking at the FAQ on 442.com to see what radiators interchange with the one in my 70W. It says I'm looking for "I" number 1169. What is the "I" number? Is it some sort of Hollander number?

I did a google search for "I 1169" and got nothing. I figured there would be some explanation at the top of the page for us "less well versed in parts interchange", but there wasn't. I know you guys don't like 442.com, but I find it incredibly quick and easy to use. So I'm trying to determine which other A-body radiators exchange with my radiator.....now how do I know which other GM radiators are "I 1169". And no laughing. )

thanks,
bob
