Lift options for 1974 C30 3+3

[RedRoad]

I have a C30 crew cab Ive been trying to sell for a while with no takers. Now with another kid on the way it looks like Ill be keeping it. I was thinking of converting to 4WD but dont think its necessary for the camping we would be doing with it and since I already have a K20 burb Ill use that when needed.

I want to keep the 8 lug as I may put a camper on it at some point or tow a trailer and want to keep the brakes but am willing to use a 3/4 coil if necessary.

Looking for around 3 in lift, way back when I used to see lift springs for 2wd offered but cant seem to find anything for early square bodies anymore. Is there a lift spindle or any other methods that can be recommended?

Thanks
