You should replace your call to get_post_custom
with get_post_meta
.
get_post_custom
retrieves all the post meta fields whereas with get_post_meta
you can specify the key of the meta field you want.
$meta = get_post_meta( $level_2->ID, 'Body Repair' );
This would give you an array with the value for the Body Repair meta key, To return a single value, you can use:
$metal key = YOUR META KEY
$meta = get_post_meta( $level_2->ID, $meta_key, true );
