i cracked my rad the other day so im going with a aluminum griffin one to replace it. my question is what size rad came factory in a L98 in 1988. the cars a GTA if that matters.

 

Get the griffin 31x19, a little work to get it in (Use the BFH)

 

The 31"X19" takes a little wedging to get it to fit, like mention'd earlier. Here's a good thread with pictures of the OEM radiator next to the griffin along with what has to be done to install it.

By the way, becareful which core size you get (you'll find out all about this in the thread).

 

the guy im getting the part from tells me there are a few options. 19" H x 3" W x 22, 24, 26, 27.5 or 31 are the sizes so i wanted to get the one that would fit best. if i can get it close without modification thats the way i want to go but if worse comes to worst then ill go with the 19 x 31
thanks in advance.

 

I sent a lot of PMs out about this also and it seems to me that a 27" X 17" would fit better. Or 27X16 or 26X16?
