69 camaro suspension upgrades

[69camarokid]

OK, so i currently have a 69 camaro with an LT1 and T-56.
The suspension has been upgraded to this so far:
KYB gas-a-just shocks
Polyueathane bushing (whole car)
11 inch discs all four corners
Hotchkis 2 inch drop coils
Z-28 reproduction leaf springs.
big sway bars front and rear
Sub frame connectors
245/45/R17s all four corners

so its not a boad start
im wondering about after market ideass for the front and rear suspension. Id like to amke the car a true G-machine, but as budget oriented as possible.

so im thinking a four link out back and maybe some tubular control arms up front?

or maybe an after market front subframe?

what do you guys think?
what parts or components would recommend or use on your own rides?
all ideas welcome!
