Well there's another strike against the CSF.
So at this point it looks like CSF = poor quality overall; Mishimoto = tons of red tape with the warranty (but haven't seen much yet to speak either direction about their quality); Ron Davis = ungodly expensive and NO warranty
A quick look on Summit came up with Griffin aluminum radiators at just over $900: Griffin ExactFit Radiator Details for - 1987 Toyota Land Cruiser PartNumber: TOY-00011 - https://www.griffinrad.com/load_details3.php?PartID=25&year=1987&make=Toyota&model=Land%20Cruiser&select_Main_Group=&select_Sub_Group=&select_Sub_Group_model=&select_Sub_Group_Engine=&select_Sub_Group_HorsePower=&key_id=TOY-00011
Haven't done any research on these yet, and they're definitely pricey but at least not as bad as the Ron Davis units.
Cruiser Corps also sells an aluminum radiator but like I said in my first post, no idea who manufactures it or of the quality of the build.
Griffin also recently changed their construction method to using epoxy now too.
