Hood hinge seal replacement
 

I am trying to replace my hood hinge seal on my 89 s10 blazer and if at all possible would like to avoid removing the hood. Is it possible to (with help) un bolt one hinge at a time and slip on the new seal? or better yet would it still be equally as effective to cut the seal and glue it back after its bin sliped on without messing with the hood at all? Any advise would be great.
