Got back on mine today.
Since I'm using the Chevelle chassis, which has the interior floor pan molded into the chassis pan I batted around the idea of using the Chevelle interior but there were a lot of fit issues.
So I decided to cut the pan from the GTO tub to see if it could be fitted to the Chevelle chassis and it was a pretty good fit.
I'll try to get a little done each day and should be done in time.
I'm including some pics of the engine mockups below as well. I had to do some minor cutting to the tranny tunnel to get the tranny to fit but less than I expected.
I'll have to fabricate a oil pan sump and some engine mounts as you can see.
