I work in a parts store and we have the ability, for some cars not all, to show how to repair or replace that particular part.
You just ask the counter person if that store has the ability to print such instructions out for you when you purchase a particular part.auto salvage yards can save you loads of money when you need a way to purchase parts for your car.
There is no great feeling as when you find out the $300 piece you priced in the auto store is only $40 in a salvage yard.
Insurance companies also utilize this form of auto parts to get rid of those vehicles that have been totaled so the recycling process can begin again for cars that are in use.It is always better to play it safe before you dig in.
If you happen to have some spare genuinely used auto parts or you know someone that might have some you can try listing them on the web.
It doesn't cost you anything and you will be rest assured that you are not wasting your money.
