I was wondering if anybody has the dimensions of the ae86 dome light, my gtsr5 was retrieved from a thief and he yanked the dome light, map light, and rear view mirror. If anybody has pictures of these items that would be helpful to see where everything was at or missing covers. I have searched, mostly google and couldn't find any relevant pictures. These are the part numbers per toyota:
Map lamp assy. 81260-16040-B0
Dome light assy. 81240-22081-08

2nd gen camry. they came in more colors too.
