Everytime I have to get a driveline part or u-joints I like to go into K-gans Auto parts Store( won't say the full name) and try to get the kid to bet me he is going give me the wrong Flange gasket or u-joints. So I give him my specks for my truck.. I also tell him that it is for the long bed with the heavy duty driveline. Not the shortbed. He replies, "there all the same." I really don't think so, comes out of my mouth . He comes back and hands me the Flange gasket that goes to my Manifold and pipe.. I look at it.. No that is not it.. "Sure it is". I'm telling you that is not the right size. The kid ask me if I am sure if this is what I need.. Ya, I need a Flange Gasket, couldn't you hear my truck as I pulled in, I just blew it out on the way here. So he runs it again and say's," that is the part required.." Look you wanna bet 20 bucks on that." I notice heads turn and a couple of employees come over to assist.. They too insist that is it also right part.. You wanna bet me.. I will bet you guys 20 bucks plus the part is free.. You guys don't have to get dirty I'll do the work right here.. OK lady your on.. So I slide under the truck, unscrew the bolts and release the tention spring coil so the old gasket falls out. When I come out from under my truck I have about 8 guys betting each other, if I'm wrong or right. So I hold up what is left of the old metal ring. Sure enough it was to small and I won.... Oh ya I need u-joints also, wanna bet on that too.. Sure enough they gave me the ones that go to the short bed trucks. As I walked out, I told them to always be carefully betting with a woman, she may get the best of you..<br />See sometimes we do know what we need, but trying to get it may take some effort..
