We used Chassis Engineering to modernise our '41 and they were very helpful in telling us what we needed to do do what we wanted.
The phone # & all was posted by MC68 in a previous thread. It's as follows:
>>Chassis Engineering's phone # is 1-319-643-2645 out of West Branch, Iowa.
Their website is www.chassisengineering.com.
I used them for my 40 Ford coupe. Good product, good company<<
Call them & see what they tell you - they didn't have an 800 # when we were dealing with them, but it's worth the price of a phone call.
