I swapped a 96 z24 motor into my 98 and the throttle body bolts smaller than the ones i had holding in onto my 98 block. I went to chevy and they said they are discontinued, I've been searching high and low for these, can anyone help? I need 1 5mm x 45mm and 1 5mm x 65mm, that's the sizes chevy told me, I don't know if they're are correct or not. Thanks.
