Re: 1991 Formula LS9 Build

The power steering reservoir no longer fits, so I had to make another.
It started as a reservoir from an Astro Van

Here is the tube installed, which fits rather tightly to everything.

It is amazing how much time is consumed on something so simple....

Next is getting the ZR1 engine cover to fit,
