Jim Hillabrand has the latest style round gear fairings on his 152, which are identical to the L-model....EXCEPT, his has the factory 'fix' Cessna incorporated into the newest design to eliminate the cracking issue. It utilizes a section of baffle material to aid in flexing at the step area.
Perhaps he'll be able to get a photo (or six) for you, so you can modify yours to match his. Cessna is getting in excess of $1400 for those now. The updated 'fix' should be fairly easy to emulate.
