Do not use a TR4 shell. The differences are many and varied. I did one once
and spent over a hundred hours on JUST changing everything from the firewall
where the brake and clutch masters mount, to rear deck arms , to B-posts, to
inner front wheel wells (The 250 uses TR6 style), provisions for mounting
brackets for IRS frame in rear beneath fuel tank, seat belt attach points,
dash area fresh air mods, handbrake mods,etc, etc. I can't even list all the
little differences. Just don't do it and you won't have to find out!
If you must, then start with a late TR4A tub, but keep your 250 tub around
until after the car is on the road, you'll be using it to cut off lots of
odds and ends, first and foremost the inner wheel arches, handbrake bracket,
and B-posts (at least the forward sections). Another option is to do what I
am doing now on a 'back from the dead resto'.... use the front clip from the
TR250, and a rear clip from a TR4A. It minimizes the mods.
Feel free to e-mail me off-list for anything else I can remember. :^)

identical I guess it depends on what extent you call a tub. I think the
common definition is everything on the steel body except removeable panels
(outer fenders, trunk, hood, doors, windshield frame). There may be some
other slight differences that I am not aware of but here are the ones I know
(or think I know):
> 1. TR4 rear sill lip around back of cockpit is thicker than that of the 4A
and 250. It also uses the aluminum trim in that area.
> 2. The TR4 right inner fender has a small triangular cutout right in front
of the shelf near the wiper washer bottle for a mating feature in the
adjacent wheel well. The 250 is straight here.
> 3. The TR4 front lower valance does not have the 250 rectangular cutout
and the TR4 upper valance has the small parking light attachment brackets in
different locations because of the lighting arrangement in the grille.
> 4. The right wheel well may have a slightly different relief for the air
filters. Not sure on this one. I know that the 250 and '69 TR6 are the same
but there is one, and maybe two, different variants in later TR6 years.
