Tracks with extended grids

[Dreyhound]

First off, sorry if this has been posted before but I did some searching and couldn't find that much so decided to get my own thread started.
Long story short, I have the cars and classes I want for an enduro series, but only 3 or 4 tracks with 60 grid slots. All I need is for someone to point me in the right direction or name a few tracks/creators to look for.
Would prefer 70's era, but ANY tracks with decent grids will help.
Thanks
