Build sheet Bingo!! 2 Buildsheets!! One is my Red Spyder. as seen in my signature.
Full Moon. Daytime Temperature this day, in the low 70's and Sunny. Low's in the 50's.
Monday, May 22, 1978: < Buildsheet numbers suggest both cars were built about a half day apart.. 298 Monza's apart (out of about 600 being built)
580 assembly jobs apart.. also about 1/2 of the average daily total of 1,100 This assembly day was just about 75% of the way through the model year.
Trim tag's:05D Buildsheet dates 05-22 80-7346
Buildsheet #1: Here we have an "XXX CUSTOMER ORDER" build sheet. from/for Mulkin Chevrolet in Brockport NY.
Chassis Number: 368872 was set to become Monza Number "198837" or the 98,837th monza for 1978. Just another one of about 550 to 600 Monza's for this day. On this 180th day of production the trim tag was stamped with an 80- and it's locked in sequence spot in line 7346 along with the above identifying numbers.
Buildsheets for the car, have a large bold 1792 which would have been crayoned in the cars licence plate area as it left the facility.
This one got many great RPO's Here's a sample..
BS1 INSUL PAKG
CD4 PULSE WIPER
G80 POSI
LG3 5.0 LTR ENG
M20 4SPD MAN TRN
N31 CUST STRG WHL
N33 TILT STRG WHL
UE8 DIGITAL CLOCK
Z01 SPYDER GROUP
Z02 SPYDER APPEAR of 6,391 spyder decal package cars, this one was about #4720 give or take a hundred.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Here, we have a dealership order, for Collins Chevrolet in Mount Airy, NC.
Another 1HR07. A Chevrolet monza 2+2. This one would not be a Spyder. But it did get a V8.
Schedule Date and number.. 80-7926 exactly 580 assemblies later that day, here was this order being built on Chassis # 363190 Now wait...
This chassis was built some 5682 before the one built first? Yep...must be that this one sat in a body bank a little longer than mine did.
Could be due to this chassis needing to set up (firewall) for A/C.
This one was painted silver then given a red interior. Floor mats, Auto trans, & N77 Aluminum rims. It was Monza 99,135. some 298 monza's after mine.
It's 4 digit lot code was 2365.. some 573 numbers later.. Thats 8 digit's off from the assembly line build order number which clicked 580 times.
Hmm.. 8 empty carriages? 8 unit's built to be shipped a different way? Unknown anomaly... either way this car would have had 2365 wax crayon'd in the rear licence plate area.
-------------------------------------------------------------------------------------------------------------------------------------------
And unbelievable....its a 3 buildsheet bingo day!!!
Next we have an Olds Starfire Built Mid-day between both of these cars. In line at 7690. Lot code 2114. A silver "Firenza!" Y65 with a black interior. Body unit number 307225 (used a body that may have been sitting in a bank for a while, or a previous number was recycled, thats some 60k bodys away) Now this could also be something to do with the fact that the Olds Firenza decal package just started being produced Last Friday the 19th!, perhaps a the firenza orders were held back until decals were ready, and or they had enough orders to start running them.
Car shipped to Okeefe Cad / Olds Westport Ct. A V8 Auto with A/C. Another "xxx-customer order" car . The 13,128th Starfire produced
309 units after my car, 236 units before the Silver Monza above. Its lot code (2114) was 322 units after mine, A difference of 13 units. And 251 units before the Silver one above. A difference of 15 units, So what we learn is there was some juggling, likely towards the end of the line, and likely caused by line "snakes" where cars with more complicated assemblies like a/c split off then returned back to the line. May have een due to Both the My Spyder and the Firenza getting decals applied while the Silver monza didnt.
Buint that the line rand roughly one car per minute, these differences were about 15 minutes in time. With the Firenze lossing @15 minutes after my spyder and another 15 min before the Silver monza was set to go, that gives it about a 30 minute delay which is about right for whats known about the decals being applied. But thats still just speculation. The side decals may have been applied along the line just as the z28 camaros were being striped at Norwood, but the hood decals may have had the cars pulled off line in an area.
That being said, theres still another unknown. The 4 digit lot code was stamped on the buildsheets as they were printed. (they must have been certain about the final line by the time of printing, and knew which cars would be meeting up in the final line unless the number was being applied regarless of the final roll out of the overhead door and into the shipping yard.
Finally it wasn't needed after the 78 model year as the 79's and 80's dont have the this number on the buildsheets. But may have still used a 4 digit lot code, wax crayoned into the rear licence plate area. thats still unknown at this time.
