The wiring clip brackets are reproduced. There are seperate left and right side ones. Our host, PY has them. Part #RPE234. Youll need two pairs.

The two temp senders are completely different units. The single prong drivers side piece is the sender for the gauge. The passenger side rear unit is for the ECS emissions system and has three prongs. Maybe someone can chime in on the part numbers. But a word of caution, the modern Delco single prong sender is calibrated wrong and will show your car to be runnng 20 degrees hotter than it actually is. Here's some helpful links on prior discussions:

My car has the fixed position 80 amp alternator, so my part numbers wont correspond to a car with the regular adjustable alternator set up. The alt belt was 50 inches and the ps belt was 49 inches long. Go to rockauto.com and punch in your application and go from there. Do you have any belts on your car now? If you dont have belts, grab a fabric tape measure the kind "the wife" uses for measuring her waistline and wrap it around the belt route. It will give you a rough estimate. The main thing to remember is to get belts of the same width, from the same manufacturer.

BTW, if you want about 81 pages more of tips, go here for the prior 1972 project. If I recall (after 8 years of posting on it) there is a discussion and photos of the two senders in there.

Did some finagling today and it fits much better.

1) I trimmed around 2 inches off the radiator end of the radiator hose. That pulled the hose bend away from the air cleaner.
2) Added the thicker carb to intake gasket. It's about 1/8" thicker than the previous one.
3) Used a couple of air cleaner to carb gaskets and used a 1/2" section of 5/8" heater hose for the top vent grommet.
4) Rotated the driver's side elbow to fully ride up against the heat riser valve. I also was able to rotate the clamp 180 degrees to fit in behind the heat riser valve.
5) I removed 2 of the 3 washers that I had under the two mounting points of the rear A/C triangle bracket, leaving only one washer to space the bracket up just enough to barely touch the valve cover.
6) I squeezed a permanent dent into the passenger side corrugated hose in the area that it passes over the unique cut out in the A/C triangle bracket.
7) The valve covers are using the correct 1/4" thick 455HO valve cover gaskets so they can clear the oil deflector cages. The regular gasket is 1/8" thick on the D-port 400, 455 engines.

Here are some photos of today's fun:

Here is how it sits now, with the bevel on the valve cover.
