Paul,

I just measured, 57.5" arm rest to arm rest in the back seat of a '93 300 SD. I know the drill, years ago I wanted a Mustang 5.0 convertible real bad. It had to fit 2 car seats in the back. Well it did, but I skinned a knuckle or two each time getting them snapped in.

I'll give you a deal on this '93, rods already prebent, 8-(, will include an '87 300D parts car with a good 603.

Chuck
