Audelio Arzola-Amaya, federal prisoner #38898-080, appeals the district court’s *596 denial of his motion invoking the version of Fed. R.Crim. P. 35 applicable to offenses committed prior to November 1, 1987. Because Arzola-Amaya’s argument concerning his failure to be properly arraigned does not constitute a challenge to his sentence, the district court did not err in construing the Rule 35 motion as a disguised attempt to file an unauthorized successive 28 U.S.C. § 2255 motion. Accordingly, we AFFIRM. Arzola-Amaya’s motions for the appointment of counsel and to expedite his appeal are DENIED.

AFFIRMED; MOTIONS DENIED.
