67 suspension height/drop question

[SilverGT3RS]

Hey everyone. I posted in another thread about completely rebuilding my front end.

Well, I’m deep in this thing and discovering little things along the way. Upon tearing everything apart, it seems the last owner was using or installed McGaughy 2.5 drop spindles and what looks like cut OEM front coils. For me, the truck as it sat was way too low. I really like the 2.5/4” stance I see on this board as the truck is a bit more useful driving around for me.
However…this truck has been C notched in the rear, and it looks like a 6” drop. So basically it originally looked like a 4/6” drop.

I’ve also decided to go with CPP tubular control arms, upper and lower.

So… should I simply go with OEM height springs all around? OEM height just on the front? What brand is good? Moog? POL? CPP?

What will I need to do on the back?


Thanks!
