The rad on my 1984 RX7 GSL SE is leaking. Few quick questions.

1. Is there any advantage or reason to explore getting the original fixed?
2. Assuming no to 1, has anyone purchased the rad from Rock Auto? It's listed as LILAND GLOBAL 97AA All Aluminum @ about $320 CDN. Would be easy and quick to get it.
3. Any other suggestions/experience for a replacement rad?

Thanks and appreciate any advice/suggestions.

 

I tried to get my stock radiator recored, and i got quoted a price that was 4x the price of an aluminum radiator from ebay. I ended up buying an aluminum radiator from Ebay (82, might be the same, but check the year compatability). The fit was good and I've had no issues.
