Build advise for a 59 fleetside

[dwcsr]

I have a 59 Fleetside Custom cab big window short bed. Its in original condition with all the SS trim cab and bed, Chrome front and rear bumpers. I've had this truck for several years now and still can't make up my mind on how to restore it. I'm torn between a complete restoration to oringinal condition or resto mod with a LSx/4l60e, IFS and some road gears. I have 5.3 and 4l60e, I also have the IFS clip that was sold by RB's obsolete, I think Kimbridge was the maker of the clip, It uses Impala parts. Cost would be about the same for either rebuild. It does need the usual rust work. I just can't make up my mind on which way to go with it. Any sugestions?
