93 300te with 94 E320 parts car

[wolf_walker]

So I've got a running driving reliable but rough 94 E320 that's basically worthless, other than it has a solid motor (with a ton of miles)
and a bunch of other good parts and I know how it's lived the last 20K miles.

There's a neglected 93 300te wagon for a grand, likely less, that's been sitting a few years with a bad trans locally.

My 94 is un-fixable, badly repaired weird accident damage to the front crossmember (previous owner).
In this very un-euro area I'd be lucky to get $800 out of it. So I was thinking I could use a slightly beat up
but un-wrecked wagon for hauling parts, dogs and kids around.

Is there any screaming reason I couldn't use my 94 as a parts car?
Will the SLS pump swap over to my motor, will my updated engine harness work in the 93, stuff like that.
I assume i can use my 94's larger brakes, and maybe swap the facelift front end parts over, who knows what else.
