After having my steel driveshaft rust through, I need a replacement. I would like an aluminum one, and I have seen them on some f-150 's

I have a supercab, shortbox. I think that is a 139 wheelbase.
4x4 w/ e4od tranny.

How long of a driveshaft do I need?
And what other trucks came with em? years?

I would like to be able to just go hit up a junkyard and save a few coins.

Thanks

 

My 95 regular cab long bed has an aluminum drive shaft.

 

2wd also? That's the only combination of these years I've seen with an aluminum driveshaft. Strangely though, my old 88 E-150 parts van had one...

 

It appears that the Gen 1 Lightning also has an aluminum shaft. Until recently I thought only the 2wd long box got one.

My 95 2wd extended cab has a two piece shaft. Is the 4wd a one piece?

 

my steel 4wd reat is indeed 1 piece.

wondering if mabye a 97-up had one that is the same legnth?
