I am looking for the dimension from the center off the yoke to edge of the drivers side cast spring perch thingy off a 78-79 Ford HP60.

Thanks :D

Damn, come on. All you fawkers running around with HP60 in your rigs and no one will answer this simple little question. What you guys can't read a tape measure :flipoff2:

Which edge of the perch, inside or out??? Do you want a straight line measure or the horizontal equivalent to intersect a perpendicular line extended off the edge of the perch???

I will be happy to measure when I get home (Jeeps not a DD)

I need the dim from the outside egde of the drivers side perch to the center line of the yoke. It does not need to be perfect, within a 1/16" would be good :D Seriously if there is room to put a straight egde against the perch and then measure off that to the yoke would probally be the easiest. Basically I am trying to figure out where my drivers side TJ coil pad is going to end up on the axle.

Thanks

I'm not sure how accurate you need this measurement to be. This is my 'eyeball with a square and tape measure while hanging half way in the wheel well' measurement:

From center u joint to outside edge of cast in perch (assuming you want the measurement of that outside edge taken all the way back to where the yoke is) is APPROXIMATELY 8.5 inches, +/- .5 inches. The perch itself is 3 inches wide, meaning the inside edge is APPROXIMATELY 5.5 inches from the center of the yoke. Of course there is more room in board of the inside edge for the u bolts.

Again this is APPROXIMATELY. Do NOT base any actual fabrication on this, measure it yourself to be sure.

Hope this helps.

Here is a real crude drawing of how I took the measurement:

Hope that was what you wanted.

Chad,

Thanks that helps and gives me an idea of what I will be dealing with. On my TJ D30 from the center of the yoke to side of the coil/shock bracket it is 6.75". Which means I have two choices if I put a D60 under the front of the TJ.

1st if I line the axle up with the yoke inline of the transfer case output then the coil/shock bracket will sit 1.75" over the top of the spring perch. No big deal I guess if it can be done.

Or 2nd I put the coil bracket on the axle tube and shift the axle over to the right and have the driveshaft half cocked.

I freely admit I don't know much about engineering coil stuff - I was lucky to do a SOA with my limited skills and knowledge and help of a lot of friends......

but I think #1 makes more sense to me. Basically you would have to figure out the 'coil perch center to center', then center those on the axle, assuming you are going to run it full width. If this means you are half on the perch.... that shouldn't be that much a problem. Build a bracket that welds to the tube just outside the outside edge of the perch, you can weld that regularily, then weld the coil bracket on top of that.

#2 only makes sense to me if you are then going to shorten the long side of the axle after that..... right?

'course I could totally be missing the point.

Are you going run it full width? Just curious.

Chad,

I think the plan is going to follow #1 and I might have to shorten the passenger side some. We will se once it gets under there and I start fabbing this up. I would really like the front to be 66" and rear 63" but everybody knows how that works.

In that case # 2 does make sense - you can leave the short side it's current length, position the coil bracket where you want it, then do all the shortening on the long side. I see. Cool.
