well its done and Bill was right its not bad at all. I bought the acuator thru a friend AC Delco 38.00 including tax part # 15-71923 and there is NO green mark on it at all and it does not come with the threaded arm. The 2 screws in the HVAC were no problem. I got at the upper with a snap-on 1/4"swivel on an extension,no problem. The wire block on the HVAC no problem. The vaccum block BIG problem the nipples all broke off inside so I threw the block away and cut the lines off the HVAC and put them together with short pcs of vaccum hose, again no problem. The connector on the acuator no problem,long screw driver just like directions said. I then pulled the 2 screws from the heater core box, mine were 5mm not 7 mm but again no big problem. Then I dropped the cover about 4" and took the acuator off again no problem. The hardest part was getting the back screw on the acuator in. You can do it by looking thru the glove box under the brace and just start it by feel then use a 1/4" rachet on the socket. the old acuators main gear was cracked in 3 places ! It now works like new ! I can't praise you guys enough or this site. Everything worked out great ! I can't believe how helpfull all of you are mostly Echo ( good talking to you ) Bill and SSE ( good talking to you too ) You guys are the best and this site is one of the best I have ever been on. Thanks again Ech,Stan<Bill and any others I may be forgetting !
