lift kits that will work.

[golfcartjohnny]

I have an early 80's EZGO, and am planning on a big block swap, and lift kit with tires.
I see these economy lift kits, and am thinking they are not really able to withstand some rough driving.
I would like to install a drop axle, but they don't make one for my old cart.
Hass anyone out there, installed a newer drop axle in an older cart, and what did, or did you have to modify anything, to make it work?
I'm new to this, and have some ideas, but am not sure about lifting the cart up, and making it durable.
Any advice or help would be greatly appreciated.

if you can weld, this was simple (for me anyway) do and fast. i use it hard too.
i will have to move my steering linkages up, but no problem. i have it finished this weekend
