slicks for a stick shifter ...

if you get the fold down back seat, shock bumpers, power steering, and especially A/C, you can be heavier than some B-bodies for sure

I couldnt believe how much the fold down seat in my fastback weighed! And the abody center console is no lightweight either.
I will be curious to see how much my 69 4sp Swinger scales out at. Bench seat, munual everything. Aluminum bellhousing and intake will shed some... But 8.75 brace , rear sway bar and frame connectors will offset that.
