Here are some photos I hope they help. This on a 72. The nut is 12mm and once loose you should be able to turn the bolt by hand with the petal return spring pressure off. This bolt operates the brake light switch also. Sent from my iPhone using Classic Zcar Club mobile

Depends on the paint. Solid or metallic? Light color or dark color? If you go metallic you need to paint the car all assembled or different panels will come out different. Dark colors are more forgiving for the amount of coats you apply but less forgiving on the body and metal work. If you paint a sold color on a disassembled car, you need to be careful and apply the same amount of coats to each part or the color shades can vary...

Cool thanks! I think I will try this

Had a dampner that looked very similar to that on my D-Production 240Z back in the late 1970's. Was a Nissan Competition number ( 12303-E4620 discontinued ) or a Tilton part. Can't remember which excatly, although I'm leaning towards Tilton. Regardless, confirmation of the accuracy of the TDC mark on pulley is what you need to establish. Set the engine to TDC using a Piston stop. Or, you can also use a long thing screwdriver inserted in #1 Plug hole to confirm when piston reaches TDC. Once you have established TDC, check the marking on the dampner. If the TDC marks are lining up great. If not, scribe a new TDC mark on the Dampner and use a dial-back timing light to set your full mechanical advance. Disregard all other markings. Note: VERY IMPORTANT. It may be worthwhile removing the crank pulley bolt and checking the overall length. The Nissan Comp dampner and some aftermarket dampners ( Tilton ) required a longer crank bolt as the dampner was thicker at the mounting face than the stock unit. A stock crank bolt will be too short to provide enough thread engagement and will work loose. I bent a very expensive Tilton crank because a " Professional " engine builder made that mistake. Finding the longer crank bolt may be tricky, but ARP probably has something that will work. The current Nissan Comp crank bolt 99996-E1065 is not correct for Dampners that require the longer bolt.
