Going The Other Way: UP?

[72longbed]

Ok,
everybody is getting real good at dropping a 67-72, I'd like to go the other way, UP with a coil sprung C20?? I already have the rear bags that are similar to ECE heavy duty bags only they will allow me to go from the stock C-20 height to about 4" higher if I want to. Now I'd like to know if the front of a C-20 can be 'bagged' to achieve a lift rather than a drop??

Anybody have experience with this or know the answer? Anybody know how high a C-20 front suspension can go before you run into trouble with alignment and 'topping out'??

Thanks for your help with this,

BTW, I'll have four (4) ECE, standard height, C-10 coils with very little miles on them for sale as soon as I get the front bag situation figured out.
