myrl883 Posted October 16, 2020 Share Posted October 16, 2020 No, mine has a dip for the dual headpipes and an almost vertical gusset on the right side as a result. Shaun - That's bizarre! Why would the FSM and the MPC have different numbers? Because the FSM uses engineering numbers, not service part numbers. Two different worlds...

myrl883 Posted October 16, 2020 Share Posted October 16, 2020 Interesting. Are you saying there are three #’s: engineering; ID; and part? That's pretty much it. Usually, if there's a number on the part, it's an engineering number. You'll never find a part number directly (stamped or molded) on a part - only on a sticker, but even a sticker number may be an engineering number. Then there are manufacturer (vendor) mold numbers, etc... It's sooo much fun. Link to comment Share on other sites More sharing options...

The gussets are marked E4TA(?)-7F and E4TA(?)-7R, just like what the shop manual lists. Can't read the crossmember due to grime and surface rust, but it probably says 5060.
