You might be pushing it, but considering that car is probably pretty much stripped of electrical options you should be OK.

I have an '88 tbird with a 75A alt - 800 class D watts, about 250 a/b. Electric cooling fans, foglights, pwr seats/windows -- blah blah -- All I have is slight dimming at high power and low rpms.

I got my 4085 for $180 shipped through crutchfield. I think the 4065 is around 130 or so there.

I think it would be very comparable to the US Ac.
