12A to 13B Racing Beat Front Engine Mount Conversion Bracket (11832)
Don't forget a bolt kit to mount this.
Racing Beat's extremely popular Front Engine Mount allows any 1974-85 13B engine to be installed into any 1979-85 12A RX-7 chassis. (The stock Mazda front engine mount from a 1984-85 13B GSL-SE engine cannot be used as an alternative due to differences in the design of the GSL-SE chassis front cross member.)
When the Racing Beat engine mount is used in conjunction with the 1984-85 GSL-SE 13B engine using any 1974-85 13B Engine RX-7 oil pan, this laser-cut stainless steel mount greatly simplifies installation.
This mount can used with either the stock Mazda engine mounts or the Mazda Competition version.
