Of course I have the part number. I've kept track of everything thing. The Trail Blazer Intake Manifold (which I bought from Amazon) is GM 12580420. When I bought it it was $90 ($89.98). Now it is just over $100 ($104). The packaging was pretty special, It cam in it's own separate case, well protected.
For information purposed, my family thinks I'm a bit to detailed (they have another name for it). When I was a young pup, a long time ago, I started keeping detailed records (now excel spread sheets) on all the vehicles I own. Which includes all maintenance conducted and parts replaced to include gas/gas mileages. At the end each year I have a section that computes MPG and cost per year. I never trade in my vehicles, I usually give them to one of my daughters/husbands along with the records. Two of them are still being driven by them and our still very strong vehicles (2008 Pontiac Vibe (214K) and a 2014 Chevy Cruze (220K)). The other vehicles have been sold/traded in the purchase of their newer vehicles. I still do the maintenance on the Vibe (my daughter is single and is dating a great man but he is not mechanically inclined), so those records are still updated. My other daughter's husband maintains the Cruze but not the records.
