At first glance without having a pan here to measure - sure looks like a 4200 with the stock pan will bolt in without mod's. I'd need to do some measurements to be 100% sure....
Hmmm now to find a straight '67 duce wagon....
efi,
My dims didn't differ from the ones Deuce posted really. I came up with 11.75 for the Bellhousing to flat of the sump and I had 23.5 for the Bellhousing to end of sump, other than that mine were the same. Parallax could be the only reason my dims differ.
