Current available heater cores

[N2BUICK]

Does anyone know if the current available heater core for the 87/87 turbo cars has any issues with the size of the inlet and outlet tubes? Someone at Bowling Green last year said the lines were reversed to original cores? I have not seen anyone speaking of it.

just contact highwaystars and youll be fine with his kit , it comes with the needed foam to pad the new aluminum core to fit snug where the old brass one was
and if you need hoses/clamps he has those too

other things you may need is 3m strip caulk to reseal the case , rtv sealer to reseal the firewall ,
you could even get a full ac case firewall gasket and cut it to replace the top of the case seal which gets torn removing the top

I took my original and had it braised at a local radiator shop. No problems since, but I live in Phoenix, so the heater doesn't see much use...
