Hi, ... I am new here. Just bought a 65 Galaxie 500XL Fastback on ebay two weeks ago. It should be here (in Germany) in about 8 weeks from now. It has the 390, but don't know if Z or P Code. Seller did not know too much about it.
My other cars are a 54 F100 with a 289, C4 and a 9 Inch (have that since 22 years now) and a 67 Mustang Convertible with a 306 (fresh built roller motor with AFR aluminum heads and other good stuff), C4 and 8 Inch.
I'll have a few questions re. the Galaxie shortly. Hope to find some answers here.
