Have you tried re-coring? I did that last year and the results have been great... Added benefit that it looks totally original and is relatively cheap at ~$400 done by a reputable shop in the SF Bay Area. Cheers! Ruben
Maranello Classic parts has them. 3000 Euro original , 1700 Euro after market. https://www.ferrariparts.co.uk Image Unavailable, Please Login
I'll vote for the aluminum Nick's Forza one. $1200-ish shipped. I put it in with some new high flow SPAL fans. Beau LeBlanc
Unfortunately it's for sale in the UK but it looks in very good condition and has a starting bid of £250 (US$ 400) Ferrari 308 328 Radiator | eBay
