WTB 4 to 1 Comp Header and Wheels

[O Racer]

Hi All,

 

I am finishing up on a rebuild and competition upgrade to my 1991 Caterham with 1700 AX block Super Sprint engine with DeDion rear, left hand drive, a car I built and have owned since new.

 

I have been trying to source a 4 to 1 competition header (1 1/2" primaries, 2" collector) from the US new or used to no avail and just got a price of 765 pounds from Caterham for a new one. Trying to come to grips with that cost, any ideas on where another might be available?

 

Also wanting to buy four new Panasport light weight racing wheels and understand the the US dealer is having trouble getting new ones from Japan. I am looking for 6" or 7" wide 13" diameter wheels (Panasport or other lightweight) with 4 by 4 1/4" pattern with 4" back space. Any help or ideas, new or used?
