sorry to here that if i could not work on my truck well they would just have to do another type of brain surgery to me. who is doing the work? if it is a shop are they reputable? the shop that works on the wife's daily driver will not use any thing from auto zone. so he will put it on for you but there will not be any warranty. so if you have to pay labor make sure you know this up front. if this is the case you might just let him use his part supplier or go to a shop that will use all Toyota parts. another option is get the good stuff and have a buddy do the work for some beer. don't give the beer till the truck runs. i think every one can work on there own vehicle if they get the right manuals. i have realized that is not true. good luck.
