They are 68 inners and 75 granada outers. The pic may be when I was trying 68 inners/outers with bumpsteer kit. The best option so far is 68 inners with granada outers on granada spindle. Bumpsteer kit made it worse since it pushed them forward some.

True,

This is looking at the driver side tie rod.  Sorry the pic is not that great.  If the cradle/rack were forward it would give more room.  Randall thought it was due to being off the ground and he was correct to a degree but it still hits it right at the furthest turning point.  If I had an inner tie rod that tracked back some that would also help.  May look at some heim joints and see if thats an option.  This rack has two different mounting points one for the 67/68 and one for 65/66.  I tried both and still had problems.

This pic is with off ground.  It is much better with wheels on ground and comes up about 5 inches.

Correct if you hit a bump it would drop but you wouldnt ever have steering at a full turn while this was occuring.  The interference only occurs at the end range at full lock.  I will try to post pictures.

Yes, I can do that.  I think most of the problem was related to not having the tires on the ground (with load).  This improved the condition but I am having to shift the rack center point to the drivers side (one-half of steering wheel turn) to get full steering range (stop to stop).

This forces me to have a longer tie rod connection on one side versus the other.

True,
Yes, it is the connector shaft (adjusting sleeve) that is hitting the frame of the rack.  It only occurs on the Drivers side.  Almost like I need an inner tie rod that has threads located behind the ball joint.  The best combo I came up with was the 67/68 mustang inner tie rods with the granada outer tie rods attached directly to granada spindle without the bumpsteer kit.  The angle of the tie rods seems to be on same path as lower arms so bumpsteer may not be an issue.  It is very close to full stock steering range which is why I was trying the bumpsteer kit.

Randall seemed to think it was the bumpsteer kit shifting it forward was the issue.  I put the car down on ground before setting toe and this seemed to help with the issue.  Removing the bumpsteer did help also.  Right at the very end of a left turn just prior to hitting steering stop, it still hits the rack frame.  I think if I shift my starting center point to the side im having problems with, I can hit the steering stop before hitting the rack frame.  It may be something with the caster/camber?  

Thanks for the responses.

Hello all,

I am installing a rack and pinion on my 68 fastback.  It is a Randalls rack (modified GM).  I have Granada spindles and having a difficult time with inner tie rods hitting rack at the very end of travel of the rack.  This only occurs on the Drivers side.  

I have tried 67/68 Mustang inner tie rods with granada outer tie rods on Granada spindle.
I have tried 67/68 Mustang inner and outer tie rods with Pro Motorsport bumpsteer kit on Granada spindle
I have tried 65/66 Mustang inner tie rods with 67/68 Mustang outer tie rods with Pro Motorsport kit on Granada spindle. (this was utilizing the outer hole on the rack designed for 65/66)

I feel like there is something I am missing as numerous others have used this setup with Granada spindles.  
All adjustments have been done with front tires raised.  I have not checked clearance with tires on the ground.  I can extend the tie rods out to avoid the clearance issue but am limited severly in turning radius.  Even with the bumpsteer kit.  

Any suggestions would be great.
Thanks,
Gary
