47-55.1 Danforth Cross Member Install - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Be careful with those specs from Borgeson & BTW, DWCSR has it right - the fractional spec, etc. is where it is at.

My first rack (2.5 "sport") with the Borgeson recuced pressure pump, hoses and metric hose adaptors (their spec) leaked at the rack - though possibly due to Borgeson sending me the wrong washers.

When I went with the 3 turn rack, I went with fractional adaptors and white O-rings from an outfit in California (similar to what Speedway sells). Works great.

Bottom line, Borgenson pump & hoses are fine, but don't follow their advice or use their adaptors - everyone but them has gone fractional.

Yes you were the one that put me on the trail for the 3 turn rack, I had forgotten your user name so I couldn't give you your due credit

Still plugging away on this install.

Threw the motor in to mock up the rack and pinion set up.

The mounting on this rack was offset to the drivers side which makes mounting a bit more troublesome. I picked up some 4" x 4" x 3/16" tubing to make some mounts out of.

Scott suggests a 3" notch to clear the rack. This WILL NOT work with a Ford rack. I had to open up my notch to almost 6" to clear the Ford rack. Frustrating to cut apart something that was finished.

I had to remove some material on the passenger side of the crossmember to clear the rack. I got a little overzealous with the skinny wheel and sawzall.

mock up

Making brackets

Tacked in

Fit test. I did end up opening up the notch after this.

Both side welded in and the relief boxed in. I just need to rebox the bottom of the notch!!
