Hi aawtech - I think the debate is still open on whether the bowtie or GM stamp is correct for 69. The part number did change in 69 to 993716, previously listed in 67 as part 987099. I have used examples of both, and they are physically the same except for the smooth texture and chevy embossed VS pebble grain and GM embossed. Attached is the 69 camaro custom accessories book and also a dealer tach sales picture, both showing the chevy logo. Also another member of this site mentioned in an earlier post finding two NOS 993716 boxed with the chevy logo.
So I'm not saying the part number 987099 is accurate for 69, but I suspect some 69 chevy's got the chevy logo until
1. mfg switched to the GM embossing and pebble grain finish, but continued packing 993716 with the prior version chevy cover
2. dealers sold out of existing stock and received the GM version. Dealer custom accessories were stocked.
Anyway - above is my reasoning for using the chevy embossed on my 69 camaro (Nov 68 build). I could be wrong of course (and still have the GM embossed cover just in case)!
