Part number conversion?

[TDW]

Anyone know of a site where I can convert the old part number in the P&A book to the modern number?

[Mr70]

I may be able to help.
What's the part #?

[TDW]

3969824 is the number. Thanks Rick.

I would also be interested in conversion info.

I don't know of any site that converts,but here is what the books show.
Cover #3969824 was originally used on the line in 1970 & up.
It was discontinued on December,1974.
It was soon replaced with #3998944 shortly after,until it was discontinued in 1988.
It was then replaced by part #14006795,which is the current # today.
All of these were used on many 1970-78 vehicles & can be found today & sell for $5-10.00 from dealers.

Hey Rick...You made that awful easy for me. I typed your number in the GM parts direct site and bingo, there it is. Many thanks. I would like to add that you are a real asset to this site. I see you are always helping with part numbers and such. I really do appreciate it. Have a good day.

Tony...I am positive he has a complete set of every part book ever made and has them in the old metal catalog holding contraptions like we used in the old parts store...

Is there any way to check if this part number 487331, is a good number, or whether it has been superceded? It is the correct vacuum fitting for my 72 T/A and I can't seem to find one anywhere. See attached photo.

487331 is discontinued, no replacement shown in my parts history catalog dated 1990

I have an old Parts History Catalog if anyone is interested in it.

Covers Chev-Pontiac-Buick-Olds-Cadillac
Jan 1, 1982 thru Nov 30, 1990.

Contact me for more info

I found some Pontiac books that show no superceded # for this part# in group 3.278..but I contacted a Pontiac "expert" of sorts and showed him your picture.
He suggested trying either part #478415 which is 1&3/4 inches long,or part #492028,which is 2&1/2 inches long.
There is another that might work,part #478417,but this is with cruise control.
These are all Pontiac #'s,and all have different measurements and angles,but he said search for them as their differences are minor and may work for your application.
Hope this helps.

Thanks for the assistance. I managed to find one on the Performance Years forum and I should get it in the next week or so. He had the exact one for my car in his toolbox!

Is there a book or some other reference available for doing the part number cross reference? I am trying to see if there is a current GM replacement number for 3906656 which is a water pump pulley for a 68 L78. Thank you.

Bill,the part#3906656 pulley was discontinued 09-2002 with no supersession to a new number.GM shows it last fitting a 66-67 Corvette 427 w/o a/c.Hope that helps.Its nice having a GM computer sitting in front of you to help people out.One of the perks of working at a dealership.
