I beg to differ here an ask why should TT132 struts be different to RT132 struts ?
yoda voice: "there is no why"
who knows why the struts are different on the TT132 THEY JUST ARE.
best way to find out if they are the strut u need is to look at the caliper.
the TT132 will have a single piston caliper the same as your TA23 the problem with this strut is the caliper bracket is part of the dust plate instead of the actual strut as well as the bolt spacing will be wrong.
the RT132 will have a twin piston sumitomo caliper. thats 1 piston either side of the disc, and u will see "sumitomo" written on the outer part of the caliper. the mount will be part of the strut and is the correct one.
as for the issues of putting them into the TA23 im sorry i cant help u with that, i always thought the TA23 had the same front end as the RA23, hence bolt right in.
