Have a 97 z28. Need to find out what size plug or bolt fits into the a.i.r opening at the top of manifold. Have heard m18 or m22. Want a definately answer not a guess

 

It's a m22x1.5 fits perfect

 

glad you got it. lol, talking to yourself,,, i do it all the time

 

Yeah it cost a fortune in wrong size brass plugs shooting into my hood. Made it sound horrible. Now just fix the 1-2 solenoid and I should be good. How hard is it to change the motor mounts. It never ends. I love the car but wtf

 

Old cars, women and kids will make your hair grey! But theyre all worth the effort!

 

trans mount is a piece of cake. engine mounts not so much. i got the passenger side one without to much problem. was not fun. mine are sagging so much its effecting the driveline alinement. doing one side helped quite a bit. ill be doing the other soon. didnt think it made that much difference when i changed the motor so used original ones.
