Howdy! I hope it turns out to have been an original Toyota diesel, but I'm betting that since it has a Saginaw steering box in it, that it was either a 5.7 gas, or 5.7 or 6.2 diesel from GM. Anybody know what GM used for diesels before they started using the Detroits? John
Its possible. The manual steering box was clearly cut out at some point and one side of the frame rail was torched and then 3/8 plate welded to the outside of it to mount the siganaw box. The fact that the badges were Toyota badges is the thing that kind of drives me to thinking it was stock... I just don't want to believe that some red-neck in East TX would go to all the trouble of finding Toyota badges to make it look stock.
Moreover, I realized this a few hours ago. It's a late 78' model and it was registered until early 84' according to the sticker. That means it was probably wrecked in 83'. Its highly unlikely that the 2F would have pooped out that quickly and a diesel swaped within the first 6 years of its life. There were no other cuts in the tranny cover to suggest a transmission besides the stock 4-speed. If a chevy V8 diesel was used, the transmission would have had to have been moved forward a few inches making the shifter hole foward...
The more I think about it, the more I'm convinced...
