I'm rebuilding my 1970 Oldsmobile Cutlass Supreme. Out with the 350 Rocket and in goes the LS1. UMI suspension all around. This is not a SEMA show car, it's a driver for fun and maybe a try at autocross.
Here is what it looked like 20+ years ago. I did some drag racing with a ladder bar rear.

Here is how it looks now.

Man I wish I had the time/space/courage to go frame off and install that stiffening kit on mine. That along with the UMI setup should be like a whole new car, will be following for inspiration. Good luck guys.

Thanks. This is my first frame-off project and the first time my son has had an experience like this.

I hope you wore gloves while using the KBS coatings, that stuff doesn't want to come off of anything! :doh::lmao:

You are correct. I did wear gloves and ruined a shirt.

Nice build. I'm building a 72 Coupe with 6.0 4L80 Swap.

Cool build, I am considering using the same parts. Trying to get ideas for my 69 cutlass convertible. Trying to decide if the brace kit is required. This car will be a fun cruiser.
