Old style cragar ss vs the new style ss

[Day2_69Z]

Yes,
I know that oh so well.
I'm 55. that being said, I was 10 in 69 & 11 in 70.....with a Dad and older brother, uncles, friends and locals living that era. I hung around,helped work on and even rode in "these real world Day 2 Cars". As I got older I was able to drive and "tune them".
What the reality brings us is a lot of these parts saw limited use and were sold or traded off for newer, better or totally different upgrades or changes.
It was commonplace for top local strip & street guys to buy / trade Used Parts that were "like new" therefore the use of 5-10 yr old pieces vs run out and buy unproven new stuff was prevalent.
Where I'm going is that today , if you find a 69 Car with 5-10 year old prior speed parts on it , most of today's Day 2 guys will scoff because "they didn't know" , they didn't "live it".
Same for a 69 Car with mostly '77-'79 parts added. They think its right.
On the flip side are cars from '69 that weren't modified until the late 70's -early 80's....
Are these Day 2 cars or period cars ?

I've had and preserved both kinds.
