This is a tool to help find TDC (Top Dead Center) using a depth gauge. I used the following depth gauge with extensions: https://www.amazon.com/gp/product/B01G9K8U5G/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1

Other gauges may also work. It is very likely that this will work with a Ferrari F355 and F430 as well.

This goes inside cylinders 1 and 8. The fit could be improved here, but it worked well enough for my needs. I was able to come back to TDC and confirm accuracy to 3 digits in my depth finder.
