Default 1969 Trans Am Correct Coil Spring

I know this has been discussed and probably hashed out before but sometimes hard to find what you know you've seen before on these threads.
What is the the MOOG Part # for the correct Coil Spring for the 1969 Trans Am
Likewise what would be used for a 1969 Non Air Firebird 400
Help is greatly appreciated.

So it is seeming like there was NOT a special front spring when you had a TA. Rear LEAF is for sure a TA only thing and so it sits lower in back. Front may be same based on a few offline discussions. Maybe the TA hood with the pan made it Slightly heavier but i have heard that from new they would be lower in the back.

Don't mix up the Moog catalog with the spring selection that came from the factory. There were a ton of different springs up front but if I remember correctly there were no specific TA springs, they were the same as the R&H option V8 springs.

69 Birds sat quite low in back, look at old TV ads or even period TV shows. With 4 people they looked like someone filled the trunk with concrete. Watch this ad on youtube:

The 69 cars sat about 1/2" lower than the 67-8 cars. They actually dimpled the axle tubes in 69 to maintain rear suspension travel with the lower ride height.
