At a loss!

The meeting yesterday with a special engineer in OSAKA SUBARU Tezukayma gave me some courage and hope to continue 20 years old first generation BC7 Legacy LSi US model.
Seriously at a loss am I which way should be chosen!
The same replacement second handed parts, ABS control unit is exhibited in YaHoo auction at 5,000 yen, reasonable price, this fact is already confirmed. With this parts my BC7 SUBARU Legacy LSi would recover an original braking performance in peace, over 10 kg weight for ABS control unit would be reproduced again, and the Legal Inspection would be passed with no problem in next January.

Eliminating ABS system from BC7 may be possible to pass the Inspection Test if the braking system was modified so long as the required braking capability might be established F/R promptly.
Just I'm at a loss which to chose, back together again as it was or the over 10kg weight reduction on the nose position anteriorly from over hung point spoiling indispensable quick steering reaction?
