I have just bought a 78 Blazer K10 That has been converted to all-convertible with parts from a 73 I think it was. The conversion looks proffesionally done and all but it also removed a lot(most) of the stiffness in the body. Whith the springs mentioned in another post, in a flexed position, I have no way of opening the doors, /forums/images/graemlins/frown.gif and certainly not closing them I can actually feel the steering wheel move in relation to the seat. How can i simply stiffen up the body? How is the original full-convertible hanling flex?
