The present invention is advantageous over the prior art in the following respects: accurate alignment is maintained between the subassemblies, even when the assembly is subjected to {HEAD ~ shock}; the stress between the alignment features is never excessive since the alignment features are employed only momentarily until the flexures are mechanically secured to the second subassembly; and the connection between the subassemblies is rigid and does not require spring force or gravity to keep the subassemblies in {TAIL ~ alignment}
