Disc brake conversion and replacing (rusty) front cross member : Questions
I’m a new Member (up here in Maine) and really like this Website/online resource. This is my first Post so please be patient
![]() I have a 70 GMC 1/2 ton short bed stepside with a 383 stroker - very fun ! I've had this truck since high school (27 years ago) – It's not a show truck but in good condition. Due to rust, I'm replacing my front crossmember, A-arms (plus ball joints, tie rods, shocks, idler + pitman arms, coil springs, etc.) and converting to front Disc brakes. It’s nearly impossible to get a good crossmember or any parts actually here in New England (re: rust or crushed), so after years of searching I found a guy (Tom) at 'Tuckers Parts' in Nevada that sold me a nice crossmember for $250 + $60 shipping. Several years ago, I had bought the 4 new Control Arms (on Ebay). My plan is to buy the disc 'kit' - after a lot of research it seems like Early Classic Enterprises (ECE) knows their stuff the best & they say they’re good quality and American parts ($859 + another $150 in shipping : for spindles, rotors/hubs, calipers, pads, brake lines/hoses, Master Cylinder, Proportion valve, backing plates, bearings). The kit does not include the ball joints or tie rod parts. I believe it's best to get the spindles/kit that fit my original parts/year (ball joints, etc.), and need the 6 lug rotors/hubs. There are many other places (LMC, 'Classic Performance', etc) that sell these kits, but they either want you to buy the ’73-87’ kit (with special tie rod sleeves, etc) and are missing the Master Cylinder, Proportion valve, or ready to install brake hoses/lines. Questions for everyone please : 1. Where did you get your disc brake conversion parts/kits ? Specifically the rotors/hubs, calipers, and spindles ? I keep thinking I could save a bunch of money by 'piecing' the parts together (the local parts store would save me on shipping costs but might be higher priced to start), but it's been difficult because it's a 1970 & 6 lug, and I want the spindles to fit the original parts. I obviously want quality parts too. 2. When bolting back on the (‘new’) front cross member : do you use a washer on the bolt head side (it appears GM didn't originally) and on the other/nut side do you use a 'washer/ then lock washer/then regular nut' or do you use a 'washer and lock nut' ? 3. I’m looking to buy the ball joints, tie rods, shocks, idler + pitman arms, and coil springs from a place called 'RockAuto.com' which seems to have nice parts/brands with great prices. Has anyone used them – your thoughts ? Thank you in advance for your support - much appreciated ! Ralph |

Re: Disc brake conversion and replacing (rusty) front cross member : Questions
I love RockAuto! The best prices and great selection. Just remember, they carry the complete offerings by many brands. The LOW grade and the HIGH grade. You get what you pay for!
Buying suspension parts just be sure to buy MOOG only! Top quality brand. There are other brands that are great, but MOOG is always great.

Re: Disc brake conversion and replacing (rusty) front cross member : Questions
Check with gmc Paul's. I have found he has the best price on disc brake kit conversion and also seems to have everything needed to convert in his kit. Paul has been great the times I have needed something. He went above and beyond to make sure I got what I needed

Re: Disc brake conversion and replacing (rusty) front cross member : Questions
Rock Auto is great,but be careful of the shipping costs.The tie rods may come from the east coast and ball joints from the west coast,shipping can add up fast.I rebuilt my front end with all Moog parts and found buying them locally was cheaper.Almost forgot

Re: Disc brake conversion and replacing (rusty) front cross member : Questions
Check with the BB vendors.They know the trucks,will only carry the best they can get and support the BB.Most have comparable pricing and all I have spoken to are very knowledgeable and will share that knowledge.

Re: Disc brake conversion and replacing (rusty) front cross member : Questions
Tom : ECE is my front runner right now - thanks
![]() Mike : I appreciate the heads up on 'Rock Auto' shipping - I did notice that when I was selecting different parts. My plan is to go with Moog too. I will get some photos soon. Thanks for the welcome to the board ![]() Guys : Any thoughts on which (bolt/washer/nut) method I should use on putting my new cross member on - which combination works best so it's strong and will last ? |

Re: Disc brake conversion and replacing (rusty) front cross member : Questions
When I bought my 67 this year, the guy thru in a ton of extras. He gave me the entire front suspension from a 71 2wd (Cross member, Spindles, Rotors, Calipers, Brakebooster-MC, Proportion Valve, all the Steering Components). Of course it was all weathered sitting outside a bit. It's cleaning up really nice, little blasting and degreasing. My brother is going to paint it all for me.
I've been told i'm better off just getting a conversion kit for my current suspension. I will eventually make the decision on which way to go. I save all these forum topics on my favorites so I can review them later. Curious to see which way you go.

Re: Disc brake conversion and replacing (rusty) front cross member : Questions
Tillik : when I learned that the 71 + 72's had disc brakes I wanted to get the parts but they rust out so bad up here, plus I need 6 lug for my GMC. Good luck with your truck !
Tinkermc : thank you and I hope this conversion (& new cross member install) goes well ![]() |

Re: Disc brake conversion and replacing (rusty) front cross member : Questions
Should I use 'backing plates' on disc brakes ? I've heard in conflicting thoughts.
