Budget Cooling ideas

any specific model of BMW. And $380 isnt exactly what i had in mind for budget.

I get them from the wrecking yard=40 bucks

5-7 series beamers, the 3 series fits perfect for the early 62-66 cars, the other 5-7 series fit the 67&up core support window perfect.

Im not rich and for me its about function more than it is about name brands or being fancy
