This may help somebody in the future save a few quid when renewing the radiator.
I shopped around for aftermarket alloy jobbies and fell off my chair with the prices they were asking. Would take 2 weeks to make too !!
I then went thru all the factory radiator books and found the exact dimensions to suit the same as the GTA....WELLA !!
Less than half the price i fitted a dual core alloy rad from an Audi.
Replaced the antique factory fan with Craig Davies twin slimlines...added some water wetta and new coolant and now she runs as cold as a nun's proverbial !!
Hope this helps a fellow Alpine owner somehow.
cheers
