thanks for all the replies. i think pulling the shaft and capping the trans. sounds right. i have to tow at highway speed about 100 miles to get to the track.
If this is going to be a regular thing, I would suggest getting a trailer.
In the '50's I drove to the track
In the '60' used a towbar
in the '70's got a trailer, then a truck to carry the car (and pull the trailer with 2nd car)
In the 80's quit racing
2000 started racing again, using a pickup and trailer.
If you have a vehicle that can tow a trailer, that is the most versatile method.
If you don't have a vehicle that can tow a trailer, it is not a good idea to towbar, as the brakes will be an issue.
