I just picked up another D44 in exchange of the D44 I picked up in Oakland that was Vacumm Assist. This is for sure is non Vaccumm assist. It came off a 1980 Waggy with a Driver Side Drop. One thing I forgot to look for was the wheel lug nut pattern. Should that matter? Does that match the Stock Toyota pattern? Educate me someone please. This one has no exchange.
