help with rotor issues

[3qtrtontarrer]

can someone help? im trying to put a set of corvette wheels on a 71 2wd 5 lug. i redrilled the rear axles to fit a 5 on 4 3/4 bolt pattern. does anybody know where i can get front rotors with a 5 on 4 3/4 bolt pattern. either new or from a doner car. tried from my 70 z28 but the spindle is to big.

this wont help much if you already have wheels.......but, you can get Vette rallies in a 5 on 5 pattern to fit the truck (aftermarket). Try Wheel Vintiques, or summit racing....... L

I have found there is one solution.. you can use a 1970 Imapla rotor which has the 4 3/4 bolt circle and is the same diameter and if I remember correctly uses the same bearings as the trucks. the big difference is the spindle on impala is shorter than the trucks, so you have to cut the truck spindle and rethread it. it is quite a bit of work to acheive the results.

We need pic's

Some early 1/2 ton vans had a 4 3/4 bolt pattern and I think the same bearings.

adapters from 5 on 5 to 5 on 4 3/4" ---- you probably need adapters for spacing anyway

come on someone out there must have converted to 5 on 4/34 without using spacers.this truck will be drag raced and want pass tech with spacers

If you swap to a 67-70 truck spindle, you can get a kit to convert to disc brakes using common car pcs. Ill try to find the link..... http://www.classicperform.com/Store/...k/6062DBK5.htm there may be a better way, but that is all i have seen.... L

I don't like the bolt on brackets for the calipers. There are lots of sources for converting to disc brakes and several posts in the FAQS on how to do it.
I will say that this site has an excellent tech help page on it and it is now in my favorites. Thanks for the link.

I have to say, that does look like a step backward.....to swap a 71 onto the old drum spindles(balljoints tierods /ect).....then use a bolt on kit to convert it back to 5 lug, just to get that 4 3/4" pattern. It does leave out the wheel adaptors tho...... back to top, maybe someone has an easier way! Best of luck...... L

ya i dont want to go backwards to go forwards. i think im going to check with a machine shop to see if they can hone out the back of the rotor so it can be redrilled. thanks for all the different ideas.
