GS4 BODY

[2foot6]

I have an early Spectrum GS4(early 1990's) with a faulty motor.The loco has travelled a few miles and I want to replace the chassis(complete with wheels/motor).My question is,will the new Bachmann replacement chassis fit into the older body without(major or any) modifications? cheers Peter.

Why not replace it with a new GS4?  Does your locomotive have tender pickup?  The new locomotives do.  You might be spending more money bringing an old locomotive up to date than a new locomotive will cost.
