any precautions before transporting, anthing I should know before toeing Options

[rfp]

If all goes well today I will be the proud owner of a 1973 914. I was wondering if there are any pre cautions before transporting it 222.miles. I was planing on using a car dolly. The car suffers from the usual rocker rust. one door slightly sticks. the guy selling doesn't know much about these cars and jacked it up by the rockers and noticed some body flex just enough to get both doors to ketch on the latches but still open and close. I'm not sure this was the best test for body integrity but he was trying to answer my question the best he new how. I have a local experienced body specialist and mechanic who knows these cars and will be restoring this one for me. over all the body is in very good condition and I am getting a fair price. I thought I read something about disconnecting the battery before pushing the cars with fuel injectors. Is this a farce or for real?
