I have made my own custom hitches, but have found it's much easier to buy one ready made that will bolt right on. I did take one hitch that had the 1 1/4 receiver, cut that off, and welded on a 2" receiver. I only used it with a bike rack or a trailer that weighed less than 800 lb.
I want to buy an older convertible car, something between 1964 to 1970. I own a Trillium 4500.
For example I found a 1970 Chevy Impala it has a 350 with a 400 turbo transmission. Should be no problem pullling my Trillium.
I can't find any towing specs for the Impala. Also I can only find a class II hitch made by Uhaul with a 1 1/4" receiver. I'd prefer a 2" receiver with a minimum class III...
Has anyone had a custom hitch made before? Can anyone suggest someone in BC, I'm in Whistler?
What are your thoughts? Any concerns or red flags?
I doubt that any 1970 convertible will prove equipped to tow more than 2,000 pounds, so see no gains in going to a "bigger" receiver. I tow a 4500 on a class II hitch without problems. It's the hitch designed for my car.
Per towing "specs" for '70's cars:
I have nothing to offer per 1970 and earlier, but this may be of some interest for slightly "newer" models:
On page 156 of the 1974 Popular Mechanics issue at this link there's a fascinating rundown of the towing ability of the "new in 1974" crop of cars.
Fun walk down memory lane if nothing else, and a few surprises- for example, who knew that the 1974 Gremlin could tow 2,000 pounds, while the 1974 Mustang II is limited to a wimpy 800?

A couple of years ago we used a Caprice to tow a 25-foot trailer on a vacation outing and were amazed that time to find out that the car, with no heavy-duty extras, was a better trailer-towing car than on any of the specially-prepared other makes we had tried.
While towing with an older convert sounds very, very cool, the same issues should be addressed as when buying an older trailer, condition, condition and condition. 60's & 70's cars, for the most part, weren't built anything like newer cars with modern concerns for handling and safety. That old chevy will drive like the QE-II and stop almost as fast. Add to that the fact that everything in it may be well over the then expected maximum age of 100,000 miles and you get to be concerned with everything from u-joints, to axle bearings, to transmission condition to ball joints to the very age and condition of the brake lines. In short, most older cars may no longer suited for those long trips we used to take without a carefree thought, especially the U.S. built ones.
About 3 years ago I was allowed to drive a 1956 Pontiac, almost identical to the one I learned to drive in. It was scary to say the least. Although "restored", and with an asking price north of $40k, it was horrible to drive, almost as bad as my 1954 Corvette, that would go any direction but straight and hitting the brakes only resulted in a suggestion to slow down by todays standards.
But there were a lot of Airstreams towed by those cars in the 60's, & 70's not to mention the 1953/54 Mercury convert used by Lucille Ball & Desi Arnez in "The Long, long Trailer" movie.
I saw one of these pulling a fairly large boat between Las Vegas and Searchlight, NV just last Friday. Top was down, driver about 70, passenger MUST have been his grand-daughter (right!) Now that was cool. (The TV, not the couple) Chevrolet SSR - Wikipedia, the free encyclopedia
