Willie59, You're all wrong! They only way to truly understand the mix is to add the gaskets together as they go together on one assembly. The AA75089 was bought. They were replaced by AA76059. You got that, I know. Then you use AA75089 on the TWO pieces that make up the one. That two and one you add together. That makes makes three. Your part number is AA75091. Added to your machine number of 580 they are assembly 75671. Then when assembly 75671 doesn't perform you take it apart. Part 75671 becomes 75091. You're with me ain't you? Since these parts are no longer usable there's no need to take apart the three and add back in the AA was once A plus A. There's no practical use for this problem solving to break it down to A37545 & A37545. SInce you've got this already figured out, you just reverse the process with A76059 which is the sum of the secondly purchase parts that are now used but cost the same as the original. But I save the 9.75% tax as this is a farm machine. At this point we have discussed only 50% of the repair as the formula for the new used gaskets which are about 22.5 miles away are not yet present nor inthe vicinity of 580CK. This perhaps will occur on the afternoon hours of 7-31-12. I will go through tthe explanation of the upcoming joining of the A38029R & the A38030R which will become AA76059RR, if necessary. I'll have to consult the slide rule for the computation of the formula of the white lightin' gasket remover and what it becomes when added it to red permatex. I'm not sure all that will be able to be included in the scientific explanation for the future owners of '67 580cks. You understand that the contamination of the hydraulic fluid, red-pink paint ($160/gal),& old permatex alters any possiblity of scientific formulation that could be included in an addendum to the factory manual. That in itself is a can of worms since the 1967 manual may have to be reconfiqured since translation may have been contaminated from you DOS program could have been used on floppy disk in an Apple2e. There's always those factors that good scientists have to consider for the future of mankind. In the interest of the sheriff's department, that are in all likelyhood, monitoring these comunications, the clear liquid in the gallon and quart jars housed in the cabinet in the kitchen are my stash of gasket remover. You trying to get me busted, willie59? Jeez, I thought any East Tennessee redneck would know better thatn to talk about embalming fluid that may or may not be present on one's property. Keep it cool with the discussions about gasket remover. Keep in touch, but on the down-low, and I'll let you know the progress. Packratc
