Thanks for the "report", Sludgeburner.

You might as well "fully identify" your truck-set-up:

"overdrive trans in my 51 behind a 235"
what make/model/year overdrive transmission?

1951 truck
what make/model/size?

235 engine
what year and original "application" (car/truck and what model-vehicle)?

Thanks
