Thanks for that but I live in Spain. Not half an hours drive away, I am blessed with the largest scrapyard in Europe. Sounds like I'm gloating but I'm not. You have to believe it to see it. I believe it has been featured on a couple of television programs. They have 3 incredibly huge hangars full of second hand components. The engines are removed from the cars after being tested, cleaned and degreased then palleted ready for sale with a 3 month warranty. You could go in there with a suit on, accidently brush past an engine and not worry about it. Gearboxes and axles are the same. No matter what manufacturer of engine you require, the odds on is that they have it. The other hangars are full of bumpers, doors, tailgates, bonnets, seats, interiors, you name it. Another has engine components, heads, injection systems, alternators, compressors etc. Its a modifiers haven.
However they only tend to put 'on the shelf' items thay know they can shift, hense the reason why there are no 'off the shelf' PB's. There are engines still in the cars but the condition is hit and miss. OK for a complete rebuild, but just to freshen up??? Not too sure if I want to take the chance.
