?s on replacement parts.

[OhioChevy]

I am about to do a frame-off restoration on my 71 chevy truck and I will
be replacing the inner fenders, radiator support and front fenders on this
truck. Do the after market body parts such as those made by goodmark,
tri-plus etc. fit up to the truck as well as the orgininal parts from the
factory? I would appreciate hearing from those of you who have used
replacement parts and if you had any hassle with using them.

I do plan on buying the parts I need from the vendors who are members
of this board and will work with me in getting the best available parts.

Thanks

Don
