Lower ball joint help
 

So I have been trying to rebuild my front-end and found that it has been swapped to 73-87 spindles with dish brakes. I have gone through two sets of front end rebuild kits and new upper and lower A arms finily got thr top half done but the lower ball joints are to big to fit completely into the spi del socket. Two sets of ball joints are both to big to fit completely into the hole on the spindle . Is their anyone who has part numbers for the ball joint that I can check fit to find the correct set

Thanks all for the info

Ps it is on air and I'm dropping a 700 horse 502 into it looking for a 6speed that can hold up to the 800 torque rating if anyone knows of anything I'm in maryland
