>> Hi all!   After too many years of sitting on an AAN engine, I finally bit
>> the bullet and am putting it into my '82 urq.
>> So far, so good, albeit a few problems.
>>
>> Problem 1:  I have conflict with the crank-position & engine-speed 
>> sensors
>> between the WX and AAN.
>> My 016 only has a hole at the top of the bell-housing for the 
>> engine-speed
>> sensor, and no room next to the crank-position sensor which sits on the
>> driver's side of the block.
>> The AAN has a single bracket that holds both sensors attached to the
>> driver's sit of the block, with the engine-speed sensor requiring
>> appropriate clearance in the transmission bell housing.
>>
>> What is the standard solution here?    I see 3 options:
>>   A.  Try to use the Urq engine-speed sensor along with cutting the AAN
>> bracket to hold only the crank-position sensor (my preferred option since 
>> I
>> wouldn't have to remove the transmission)
>>   B.  Cut the side of the transmission to enable proper fit of the AAN
>> engine-speed sensor
>>   C.  Enlarge the hole at top of the 016 to accept the AAN sensor in that
>> 016 location.  The sensors would need to extend to the same depth.
>>
>> Thanks,
>> Eric
