i was just woundering if anyone has ever seen or heard of an elcamino with something like a front clip from one moddle year and a rear end from another? also i was woundering of someting, but yits probly not possible without a ton of work, but could i buy all the body peices for a 59, front end and rear end ect... and put them on my 86?

there are conversions for same gen. models (78-87 Camaro to Elk) and even body kits to make it look Italian (Lamborgini) (didn't think I could spell it did you?)
But why in the world would you take a 86 and make it into a Batmobile?
if you like the '59's, trade the '86 in for a First Gen.

Another possibility is to learn body work and make your own wings and such, Doing this will allow you to fade everything in somewhat gracefully
(just can't picture grace going from 1st to 5th gen)

One thing to consider is if your grandmother helped you get the ELK, keeping it original will hold more value for you (personally) later.
