from to on 4-door hardtops. To reduce development and tooling costs, and bring overall expenditures more in line with actual sales, Imperial began to share some of its bodyshell with the Chrysler New Yorker for the first time since 1956. Consequently, glass and roofs were common with the entry-level Chrysler Newport. In other respects, however, little had changed; construction was still unibody, the wheelbase was still stretched longer than a Chrysler's in front of the passenger section, the engine and transmission were the same, and the torsion bar front suspension was still used. 1969 (Series EY-L,M) In keeping with the times, the look was sleeker, with a reduced, more subtle level of trim. For the first time, the lights were hidden behind doors, giving a fashionable at the time full-width grille look using "loop" bumpers. Only this year the Imperial featured sequential turn signals. 1969 was the final model year for pillared sedans, and it was also the first year for the Imperial LeBaron coupe. At , the Imperial once again became the longest non-limousine car made in America, and would remain so through 1973 when it would set the post-WW II record for non-limousine car length. A total of 22,083 were produced, making it Imperial's third-best ever year. Ambruster-Stageway of Fort Smith Arkansas continued with limousine conversions using the 1969-71 sheetmetal.

A wide chrome strip was added at the rocker panels, vinyl side trim was made optional, and (for this year only) the fender skirts were gone. It was the final year for the Crown series and this was the first year the LeBaron out sold the Crown. Imperial had only two models and styles of Imperial for 1970. A LeBaron hardtop sedan and coupe and the Crown hardtop coupe and sedan. 11,816 of the 1970 Imperial's were produced. 1971 (Series GY-M) For 1971, the Imperial Eagle at the front of the hood was gone, replaced by the word IMPERIAL; the decklid badge said, for the first time, "IMPERIAL by Chrysler" and the only model offered was the LeBaron.
