I agree on putting the engine in First. Be Careful lining up engine and tranny. I had a disaster when the oil slinger came loose amd got caught in between the engine and tranny - do not pass go do not collect and it cost me a tranny too. On the next round I replaced both together just to be positive. Change the shaft seal! If you do the tranny replace the front and if possible rear bearings I'm told they are available at bearing places. Take lots of pics and label Everything. Keep organized! I found that MAP gas and [ower blaster works good with tightening by jarring first.
Any news on ways to brace the back wheel wells? It's true they are not real strong and I have not figured out how to do it.
Is there a picture of the whole car?
Midwest Fabrics has the cardboard material for the panels. I made my own and used older Ford fasteners to affix them to the door. It worked great.
