Thank you all very much for the birthday wishes

A working man's realistic restoration. The truck looks excellent. Continue to be happy doing what you're doing and most of all cherish the time spent with your dad and uncle. I can see they taught you well.

God is great, b-model's are good, and some people are crazy

Hey Red Horse,

In reply to your CT trivia question I believe that the answer is Debardinas. Spelling close enough???

I have a B-613 cab on my "58". And I have been searching for the same type of cab to marry up to. For a crew cab conversion. How do other model B's compare in contour and dimension's. Thus, would any B-model match?

Thanks'

This project should give you all the information you need.

Alright guys you helped me out before and now i have another question for the pros. I am doing a 68 DM600, pulled out my 673e and installing a 675, i am keeping my quad box trans so i have to keep my old bell housing. Question is the dowl pins that would center my bell housing have slop in them. I have heard that you are supposed to install it and put a dial indicator on the crank to make sure it is centered, then just tighted the bolts. In my mind doing this would work but wouldnt this put all the stress on just the torq of the bell housing bolts, dont you need the dowls to actualy support and keep the motor from shifting? As always any input would be great and if you need more info let me know. Thanks

Yes, you are correct to the point of dial indicating the bell housing to get on center and tighten the bolts. The dowl pins are critical in the support of the bell housing and transmission. After centering the bell housing and tightening the bolts, you should purchase a new pair of oversized dowl pins. Then redrill and ream existing dowl pin holes in motor and bell housing to within .002 to .003 smaller then new dowl pins diameter. This will allow you to drive new dowl pins in their bore tightly.

Note: Check bell housing face (engine side) for any wear due to previous loosening. If so, I suggest having bell housing machined to remove any wear and true up. Also check back of engine block for the same problem.

Hope this helps!
