lowering kit

(1/3) > >>

73 CORV:
:Can anyone advise me where I might be able to pick up a lowering kit eg;lowering bolts for a 73 coupe in Australia. Cheers

Vettech:
You might try Ian at ChevParts Yenora, or Pontiworld down Albion Park way. I know I bought bolts from Chevparts many moons ago, but these were normal length, which still have some adjustment. Plus new rubbers/bushes etc.

73 CORV:
Thanks champ I'll give them a try tomorrow.

standard bolts are 8" long.
you can buy  grade 8 bolts at any good industrial bolt suppliers.
Make sure you ask for grade 8 do not accept grade 5.
you will need UNF thread and nilox nuts ( I like grip nuts they are more reliable and you can buy them hardened. )
 
  grade 8 will have six makes on the head of the bolt

 this will help
how far do you want to lower the car.

Vettech:
Oh, the reason I changed the bolts was that whilst doing something else I noticed the "originals " were rusted and bably collared, plus the rubbers had turned into concrete, I would imagine its a good idea to replace these at reasonable intervals. And yes Bob is correct they must have the five marks for grade 8.
