Marty,
Looks to me that the crossmember and the steering rack are pretty much the
same position in both my 6 and my TR4A. The crossmember bolts to the same
place on the upper spring bracket on both as far as I can tell and the
steering rack is directly under the crossmember on both.
I think the 4 banger engine is just shorter....maybe they knew something was
in the works, e.g. a 6 banger engine. Looks like the fan extension is quite a
bit shorter on the 6 than the 4A and maybe the even damper/pulley is thinner
(I couldn't get a good look at the one on the 4A...too much junk piled up) on
the 6 engine which just by eyeballing it looks like the difference would allow
for those two extra round holes. The damper is a lot further from the
crossmember on the 4A than on the 6.
If the TR4A and the TR4 frames are different (which I can't answer) then all
of that info. doesn't apply.

Subject: [TR] TR4 & TR6 question
Does anybody have both a TR4 and a TR6 in their garage they would be
willing
to take a look at for me? By looking at two frames it appears that the
steering rack and cross tube are mounted farther forward in a TR6 than on a
TR4. I am going to guess that this is to clear those extra two big round
holes
in the TR6 block. I am looking for confirmation on that. I also need to
determine what issues I might run into by moving the rack forward in the
TR4.
It worked in the TR250 so it's somehow possible (I think). Anybody have
time
to take a peek for me and tell me what you see?
Thanks,
Marty
