Doing a bit of research on the JP 2002 reissue 'New Year Special' Alert (Red Alert) & Lambor (Sideswipe). Found out they are cosmetically slightly different to the standard G1 reissues.

Courtesy of tfwiki:
Lambor (Sideswipe) and Alert (Red Alert) were once again re-released together in January 2002 as an e-HOBBY exclusive "New Year Special" set, with several factory-applied decals replaced with paint operations, the "CAR MACHINE" plate-decal now blank, plus an additional recolored alternate sticker sheet for each one and bio cards with new art by Hidetsugu Yoshioka.
Again, courtesy of tfwiki:
For 2002, Alert was again released with Lambor, this time as "New Year Special" editions available through Takara's e-HOBBY online shop. This latter version featured yellow instead of blue stickers for his shins and feet.
