G - GM
2 - Pontiac
A - Seatbelt restraint
W - Trans AM
87 - 2 Door coupe
S - 305 ci V8 LU5 (1983) (Cross Fire)
? - Check Diget
D - 1983
L or N - Van Nuys or Norwood
2 - Pontiac
xxxxx

whats the problem?

 

thanks okfoz
your decode matches what i have! several other decoders on the net are bogas!!!
do you have any production numbers for hard tops produced as pace cars?
read somewhere only about 160 made thanks again and have a great day

 

WAIT !! You say you have a hardtop top '83 datyona

If you do,Take care of it cause only 2 have surfaced recently.

Try and post pics and data plate info if you can.

 

3rdgenparts hi
yes i recently traded a 66buick special for a 83 daytona hardtop 97000 miles but it needs a lot of work. 40 mph top speed on delivery gutted the cat and tweaked the valves speedo now pegged before third shift. to be worth taking pics needs new hood, pass fender was told encountered a deer and drivers quarter has some cancer starting. the front seat covers are shot the motor runs but the cam is flat and the bottom end ratteled like mad when i changed the oil, the car drives execelent with no under body rust when i checked it out at a buddys muffler shop. i have been searching for seat covers for the recaro's or some one that can copy them with out selling my first born. i am planing to swap out the 305 for a hot 350 i built a few years ago for a sleeper station wagon and keep the crossfire, hooker shorty headers and custom duals but trash the smog inj system have been wondering if i should keep the old engine for numbers maching car value but need more info on this subject i do not plan on letting this car go it's a keeper and should look like new by spring. any help on locating more research material is greatly apprecatied. have a great day and stay safe chuck

 

3rdgenpartrs
ps the data plate you wanted it the one on the rad support correct? will check back chuck

 

Yes that is correct

 

3rdgenparts i have the plate # for you i'm not sure on decode but will try to match what i have here
D 01B 2FS87 N 211501
604 11L 11U 82ME
A09
Y82 N09 D80
055140 586769
it is very confusing the windshield vin is 1G2AW87S4D211501
i thought the third set of body # should code for a ta
i don't know where to look for more plates no build sheets in seats or kick panels also inspected both doors but car has not had a repaint just some touch up on the pass rear quarter.
still have not found info on if the block # should have a partial match also.

also what to thank okfoz again for the in put
i can use all the help i can get thanks again chuck

thanks okfoz i will pull the alt. tommorow and take a look found out the rear axle housing was swaped out for an 86 unit the salvage yard paint was a dead giveaway planed to pull the cover and check the ratio so i know what i've got.
thanks for all the help.
p.s. do you know 84L69TA have been trying to get in touch on some parts he has for sale no responce

 

Rather than pull the cover, why not simply count the turns??? Not as accurate but it would give you an idea...

A 3.73 gear for example, you would turn the driveshaft approximately 3 and 3/4 turns to get a wheel to turn one time.

John

 

actually on an open diff(if its open) it will have to multiplied x2 since the axles/wheels will turn opposite directions the same distance/amount

 

john and fast68
i figured it needed the gear lube changed anyway plus wanted to make sure has a posi unit in it, never know what you have when you find salvage markings just checking the brakes found one early caliper and one late one and the late one's e brake is locked up inside and won't adjust
thanks again and have a great turkey day
chuck

 

yep yep, i agree

happy turkey!

lol

 

If you spin the pinion gear and nothing is touching the wheels, it should not matter, as both wheels should turn at the same speed... IF you stop one wheel from spinning then it would be double...

If that is the case then spin the pinion one time, count the revolutions of each tire, then add them together if different, then devide by 2 to get the ratio...

OR just change the DIFF lube and count the teeth .

John
