I know I'm a little late to the backwards bolt party, but another way you can take it out is to drop the ps pump off the engine and use about 18" of extension under the rear manifold. Had a guy show up once w/o his wheel lock, motor still came out

For others that might read this and not understand the difficulty of finding this bolt. Once the diff bracket is out of the way here'* the view coming in. Look for the silver dot right above the disc brake.

Ahh, those are the pics we needed so bad here Bill!

We need to do a write-up for Tech info on this darn bolt!

Check the rear exhaust manifold and make sure that the downpipe is in the same location.

All sensors must be swapped over.

I agree with Jon. When I swapped a 97 engine into my 95, the rear exhaust manifold down pipe mating flange was different. Ended up swapping manifolds.

OH! Leave the oil pressure sensor off the engine until you are completely done with the install. They tend to break when dropping the engine in.

Swap fly wheels to be on the safe side.

You will have Check Engine Light nightmares!

You'd be surprised at how often they change parts from year to year on these cars. The 95'* are a rare breed.

OH!! Keep the 95 throttle body and the MAF sensor. 95 was the only year that has their own type of TB. You can tell the difference between 94/below, 95, and 96 and up. The MAF sensor will not fit on any other year besides the 95.

I almost haveit in and I am curious that because I didnt have any of my original sensors to replace them with assuming mylight does comeon would I be able to get it reprogrammed to meet the motors year or should I replace the ecu with the matching year?

Changing a 95 PCM to a newer year is more trouble than its worth. On 95'*, the PCM is located under the passengerside dash. Newer PCM'* are located in the engine bay now.

I'm not sure if reprogramming will work either. I do know some sensors will not connect to your existing harness. ie, oil level sensor, A/C pump has a connector.

If you tried to upgrade to a 97 PCM(not sure about 96) but the 97'* have a second O2 sensor while the 95'* do not.
