You might say , I'm old school . Like when it comes to rebuilding machanic all devises , I do everything I can . For instance : gaskets , I never bought anything other than exhaust or intake for internal combustion engines . I made every gasket I ever needed with a brass ballpene hammer or hard plastic for aluminum . THE QUEST : I needed some gasket material that would exceed 600 degrees . Old school , no problem ! I set old looking for a role of gasket material ...... ....! After three days of searching every auto parts store , I finally found what I was looking for . 16" wide by 24" long , $32 ....? Ok , I have enough to last my life time ....! Next item: 1/2 ohm resister .... On line , I had to You-Tube a video on how to make one ! Next item: Shrink tubing , about three inches worth . In my day , about $.23 .....! I found a multi-pack for , (drum role please) ......$16 ......! Sixteen dollars ......? You go broke no matter what you know but all in all , I probably did save myself $1000 ! One of the problems was a "air bag censor" on my truck . I have heard of people paying over nine hours labor to pin point this problem . Well , I guess I did ok after all ....!
