I replaced the manifolds on my 3500 (Auto) with SD1 manifolds (larger bore). A new set of down pipes were required (to suit larger bore on manifolds). Here Colin Gould sourced these down pipes (in S/S), along with the reminder of the large bore system in S/S
Hi, I used 3500s manifolds on my series 1. I purchased new ones from JR Wadhams. I purchased a stainless steel exhaust from PD Gough. It fitted excellently. Good luck.Hi,
My manifolds are cracked. Now I could buy new ones for a 1971-1976 3500s, but I have a 1971 3500 series 1.
Will the manifolds fit my car?
Best regards,
Joerg
Sorry Harvey, just re-read my post. I used 3500s manifolds (not SD1) - typo.So you had twin downpipes each side coming down at about 45 degrees towards the bulkhead, joining into a single pipe each side?
I had thought about doing that but never thought there would be enough clearance.
