According to TFWiki the Super Ginrai and the Godbomber toys can be combined to form God Ginrai. The two of them were sold separately and together as a gift set. But I don't see a mention of his sword.
Super Ginrai was also sold in a gift set with Godbomber, who can
interact with Ginrai in several ways. Trailer-mode Godbomber can hook
up either directly to Ginrai's cab or to the back of Ginrai's own
trailer and be towed along behind him, while any of Ginrai's weapons
can plug into the holes in Godbomber's wings and chassis. Most
prominently, of course, Godbomber diseassembles into various component
parts that combine with Super Ginrai to form God Ginrai. Godbomber's
legs become boots known as "God Legs", to which Ginrai's Particle Beam
Cannons attach; his chest and wings form the "God Wing" backpack; his
arms clip over the top of Ginrai's own as the "God Punch"; and his
back becomes a chromed chestplate called the "God Breast", into the
top of which the spring-loaded, missile-firing "God Cannon" plugs. The
toy also features a secondary, lesser combination referred to as the
"God Breaster", which involves attaching the God Breast to Super
Ginrai, and plugging Godbomber's wings into his arms.
