Re: 1985 Trans AM w T-Tops & 5-Speed Manual
If you’re actually trying to sell this car, why are you only showing the $200 in random parts you bought??? No one is buying this car because you are including replacement wear parts. Post some pictures of the whole car - interior and exterior.
You’ll also probably have better luck posting this in the classifieds Cars for Sale section (if you haven’t done that already).

That’s fine. I think you’ll have a better shot at selling if people can see the car they’re getting. I’m just trying to be helpful.

Were there ever any pictures of the actual car ? I don't seem to see them. It's like trying to sell a house and you post a picture of a rake in your garage.

No pics of the vehicle have been posted yet - just the parts I assume you’ll get if you buy the mystery car.

It’s the AutoZone Limited Lifetime Warranty 
I only paid for the Radiator Cap @ $8.49 +10.250% LA County Sales Tax = $9.36
I’ll edit the caption to reflect $0.00 for the Radiator.

Well, speaking of the AutoZone Limited Lifetime Warranty 
I returned a replacement Water Pump from my retired, 1990 Trans AM for $31.99 in credit towards my purchase and I paid the difference.
Heavy Duty Water Pump $33.08

Re: 1985 Trans AM w T-Tops & 5-Speed Manual
More cost-savings via the AutoZone Limited Lifetime Warranty 
The Coolant Temperature Sensor was no-charge and the Thermostat was covered with my AutoZone Rewards. The EGR Valve was removed (post #18) so the TV Switch will be blocked-off with an Aluminum Plug. A 160F or 71C Thermostat was selected from Moto-Rad which is the same Brand as the Radiator Cap (post #11).
Temperature Coolant Sensor $0.00, Thermostat $0.00, Thermostat Housing & Gasket $16.53, Thermostat Gasket Sealer $2.19, Thermal Vacuum Switch Plug $4.54 and Thermostat Housing Bolts $4.83 (not pictured).

The price difference between an aluminum & cast iron Water Pump was only $1.00 but had to be special ordered, so the previous Water Pump (post #17) was returned.
Aluminum Heavy Duty Water Pump $1.11, Water Pump Bolts $10.40 & Lock Nuts $4.40 (both, not pictured).

Re: 1985 Trans AM w T-Tops & 5-Speed Manual
In the Coolant System overhaul I’ve saved a lot of money through the AutoZone Limited Lifetime Warranty 
Therefore, I splurged on these solid billet 6061-T6 aluminum pieces from March Performance.
Alternator Bracket $80.47 & Bolts $10.81
Water Pump Pulley $97.01

Re: 1985 Trans AM w T-Tops & 5-Speed Manual
Unfortunately, the project is at a bit of a standstill at the moment. My OCD derailed the Coolant System overhaul as I've spent too much time polishing the Water Pump.
Updates to follow, hopefully sooner than later...

Re: 1985 Trans AM w T-Tops & 5-Speed Manual
Many Moons ago, I bought a set of USED Doug Thorley Tri-Y Headers (#375Y) and had a Thermal Ceramic Coating applied @Embee Performance.
Needed some Adapters, Gaskets, Hardware & Spark Plug Wires for the installation and @Team C Performance in Bellflower had them in-stock.
Header Adapters $38.57
Header Gaskets $30.86
Header Bolts $18.72
Spark Plug Wires $60.58
The best price I found for a shipped Intermediate Pipe was from AP Exhaust - XLERATOR X5500. Which is a nice 3” mandrel bent pipe made out of prime steel.
Intermediate Pipe $93.26
Displeased with the Exhaust Hanger from the Intermediate Pipe being cutoff and replaced with a generic Exhaust Hanger bolted & welded to a different location. Would rather have utilized the original design and location because now it’s crooked!
The Muffler was also a great price! Chassis specific since it’s a FLOWMASTER 80 - Series Street Muffler 42583 for single inlet & dual outlet.
Muffler $50.00 / Tailpipes $71.14
Labor & Misc. Parts $900.00
Labor was performed by Express Auto Repair in Bellflower, CA.
The OEM dipstick was replaced.
Installation of Starter; I choose an updated LT1 design (post #38) which required a NEW positive Battery Cable & Battery Terminal Adapter to be fitted and routed. Unfortunately, this was very poorly done and I’ll need to redo.
Installation required a NEW Clutch Cylinder due to an issue that arose from its proximity to the header (post #39).
The Y-Pipe looks like some generic piece from overseas.
Needed some Adapters, Gaskets, Hardware & Spark Plug Wires for the installation and @Team C Performance in Bellflower had them in-stock.
Header Adapters $38.57
Header Gaskets $30.86
Header Bolts $18.72
Spark Plug Wires $60.58

Kudos to the AutoZone Limited Lifetime Warranty 
I returned a replacement Starter from my inactive, 1989 Firebird Formula 350 for $96.99 in credit towards my purchase and I paid the difference.
& $1.28 in AutoZone Rewards for the Design Engineering, Inc. Versa-Shield in an attempt to preserve the Starter from any heat not contained by the Thermal Ceramic Coating.
Starter $83.22 & Heat Shield $27.37 (not pictured).

Re: 1985 Trans AM w T-Tops & 5-Speed Manual
The installation of the Doug Thorley Tri-Y Headers (# 375Y) encountered a major hurdle due to the Clutch Cylinder coming into contact with the Header on the Driver’s Side. The issue was two-fold as the original Clutch Cylinder was made of plastic. Therefore, an aftermarket design in aluminum was selected. The original Clutch Cylinder Shield could not be reused. So, some Reflect-A-GOLD high-temperature heat reflective wrap was used to minimize the heat transfer. The header primary tube also required a small dent to avoid direct contact.
Clutch Cylinder $44.09

The Power Steering System overhaul was complicated by some incorrect product descriptions & part numbers on Amazon and numerous belt exchanges @AutoZone due to sizing.
Power Steering Pump $39.68, Power Steering Pump Bracket $0.00. Not pictured: Power Steering Pump Pulley $0.00, Power Steering Pressure Line $24.24, Power Steering Reservoir Cap $X.XX, Power Steering Return Line $X.XX

Pretty rare those are not disc and posi. Now that i think about it, i believe only the drum units were open diffs. I know i read that somewhere.

The original Hood decal had faded and it was cheaper to buy another Hood with an aftermarket decal then replace the decal.
