i know this post had to have been on here more times than anyone can count, but here goes my question, on a 71 demon want to know if you can mount rack and pinion on a stock k member and possibly make it front steer, swapping the spindels from side to side. i have heard different stories but no documentation. i dont have the $$$ to buy tubular k member and all the goodies trying to get r done on the cheap. any and all input appreciated. sorry for rehashing an old subject, i did a search and didnt have much luck. thanks

I think Bondo Bob has a set up for that type of application

Jim ,I did it! But the Kmember is no longer stock. In the Stock Kmember you cant get the rack back far enough for the geometry to work well.

You can get around this for some $$$, but my advice would be just use a stock manuel aluminum box and be done with it.

The front steer rack can have its advantages over the rear steer manuel.

Header clearence is the main advantage. Weight is not. mike

sorry but i beg to differ. zero bumpsteer & very positive steering on my junk. only drawback is you need to make a custom oil pan but that just meant i could improve on a stock std unit.

the original rack install was done by a pro who raced an A body in curcuit racing & he was in the top of his field. i just had too much time on my hands one day & made the hole bigger, but that meant i could build a bigger pan but not so deep.

with this pan i made i have zero oil problems. i have my oil warning light set on 30psi & it never comes on during a run.

I dont recall what Bobs system costs, I think $1500 or so. I know he has it worked out pretty well though. With Alot of Work!!

But since you stated you dont have the bucs $$$.!

Even on the Cheap!,

Slapping a front steer Rack and Pinion in a stock K Frame is going to run you about $450 bucs with everythings thats needed.

Thats just for starters, Now you have to learn how to make it work.

That will include more Labor and more $$$ and if your as Dumb as me a few more Years mike

He Stated Front Steer.

He also stated Stock Kmember, witch yours is Far from mike

Stock K frame with the same setup...and yes, mine as his was RHD...



A buddy of mine with a '68 Charger R/T with a Hemi in it is running the same setup, but using a power rack.

Very common swap, been done in Oz for years using a Holden rack which gives no bump steer issues, etc.

thanks for the replys, i can handle the 450.00 alot easier than the 1500 to 3500 they want for there systems. dont get me wrong i have looked at his stuff and it is bueatiful. but if its not in the cards than the only way i can get it done is to do it then thats what i have to do, i am having header clearance problems that is the main reason for front steer. how much did you have to remove of the front k member to get the rack in, and what about mounting the rack as far as hieght in relation to the tierods ?

My dad built a rack&pinion into his 68 Valiant with a stock K-member. Front steer, the rack is tucked up into the K-member a bit.

Your Dad knew what he was Doing!

With a Front steer the Rack has to be that far back As pictured to work right. A stock oil pan wont allow that.

So theres another mod that needs to be done $$$. It really cant be done properly on the Cheap $$$, More like $$$$.

Unless you can Fab all that stuff yourself, and dont count your own labor , then it will cost you only $500 bucs or so. mike

thanks for the pics, have you driven the car yet, was wondering about ackerman effect and if you have bumpsteer. some say yes and others not having trouble. the cross member looks great
