Good fit and appears to be a quality man
I bought these perches to be used with my original 31 front axle and a new reverse eye leaf spring. This perch fit both of them very well and they have a nice look to them. They have a nickle finish on them I believe which would look good unpainted but I am going to blast and paint them with my frame anyhow.

very nice
these are very nice, BUT, these need to be beveled on both ends. Only the top is beveled, they need to send 2 beveled washers with this, to make it complete. Other than that, they are nice.

Can this perch be used with a 2 inch wide leaf spring? If so what additional parts are needed. If not, do you offer a wishbone bolt/perch for a 2 inch wide spring. I need to run a 35-36 inch long spring and have only found it available in a 2 inch wide spring. I am using a 1942 passanger car axle and want to mount the spring above the axle instead of in fount of the axle. I am building a fenderless model t hot rod for the street. Using oem 1942 wishbone, split to attach to frame rails. The simplest thing might be to use a 1.75 inch wide by 35 inch long spring, but have yet to find one. The distance between the wishbone to axle boss centerlin is about 41.5 inches. Thanks for your help

I bought the I-Beam split wishbones kit (91639526) that included the spring perches (91033047) and lower shock mounts (91036105) which have a key way on the perch and slot in the shock mount but the is no key included in the kit. Is it necessary to have a key installed to keep the shock perpendicular to the axle? Where can I purchase a key if needed, from Speedway or an auto parts store? Overall the kit looks great and was shipped 2 days after ordered.

I have a T speedster with the front spring mounted more-or-less in the stock configuration, the spring being perpendicular to the frame. Can these perches be bent, cold or hot, to adjust for caster? Original perches are about 5 1/2° off from being square to the bolt/shaft section.

Why is there no key way in the spring perch to match the lower shock mount key way such as part # 910-36105 I purchased a front end kit back in early 2013. I am now working on shocks for my 1932 ford pickup. I called speedway back in mid 2013 when I installed the kit and asked about this issue. The tech told me you weld the two parts together. Ok I'm new to this back then, I dropped the issue. I have learned a lot sense then. It just doesn't make sense to have keyed and not the other.
