73-87 SPID question

[jocko]

Awesome - thanks for all the help guys. I'm a 67-72 guy by trade (and a 60-66 I guess), but sq bods are growing on me! Been poking around for a 76-79-ish K20 and was speaking with a little old lady that has one for sale on the phone, trying to direct her where to find the SPID (she insisted on going outside and looking for it - with emphysema, I BEGGED her to not worry about it, but she grabbed her LOX bottle and went wandering out into the driveway anyway, hacking up fur balls all the way, I felt horrible...) ANYhoo, she said the glove box was bare, so I didn't have the heart to ask her to look under the hood. She might have keeled over... Thanks again for all the replies, you all definitely answered my question.
