F body rad. update question

[fritz]

just got back from the AutoZone, ready to buy the #433918 spec at
1 row,26 1/4 x 17 1/4 x 1 5/8 core size OEM replacement for the 90 IROC. 116.99

But they also list as an option for the same car
#433918 "option" spec at
3 row, 26 3/8 x 17 x1 5/8 core size
118.99

Seems to me that for the 2 extra bucks, the 3 row is a better way to go??? Diemensions are close enough to work???

thanx for the help.

Did you punch in a typo there? I have the radiator catalog of the brand that AZ sells and 433918 is the aluminum with plastic tank and 438918 is the other number listed and that is the old copper/brass job. That should be what the difference is. I would think a 3 row aluminum rad would have a width 3 times that of the single row.
