dustaboy74 OP member D Joined: Jul 2004 Posts: 106 The NB Vermont	I was wondering what you guys did to your stock k-members and what you would recommend. Pictures would be great. I am currently building a 74 duster into a drag car and am looking for ideas to what to do with my stock k member. I will most likely becutting the motor mounts off and cutting the k member and boxing it but just wanted to see any other ideas that have worked well for others. Thanks

My buddy welded flat stock where the K was cut. This pic was when I yanked it all out to put the AlterKtion in...

My last one had the motor mounts removed and notched and boxed for the oil pan. I think one member cuts the whole center out and installs a piece of 2X3 as the cross piece.

If I would do it again I would cut it wider and deeper towards the front. Would make getting the pan off or even putting the engine in easier, deep pans suck. Make sure if you do decide to do surgery on the cross member either leave it bolted in the car or weld it to a heavy steel bench to keep it from warping. it's ok to butt heads, just don't do it with a butthead

I think you have the right idea ... if you're going to start hacking away the k-member its easier to fab what you need rather than carve off what you don't need. You've given me some ideas !!

Looks good, but how is the pan clear... with all this room i made a special pan. the base is flush with the bottom of the K frame & holds 10 litres which i think is 12 quarts. no running out of oil for me. engine fitment is REAL easy. 5415628-Picture1352.jpg (88 downloads)

The only purpose is to mount the stock strut rods. Why not use a tube from one side to the other with tabs for a heim-jointed strut rod ??
