Well I decided to buy one for the hell of it it's made by thermal solutions manufacturing part number is 399233 it's made in Mexico quality doesn't look that great the solder joints are excessive where the core meets the end plates but it seems fairly heavy duty I don't have it put in yet but I'm hoping it works better than the one I've got which is just the cheapest I could find on RockAuto from 4 years ago I don't think it's worth 150 bucks but for copper heater core what other options do you have I didn't put pictures up but I have no clue how to do that
