Tube shock conversion for 1940 2 dr

[past gas racing]

I have a '40 2 dr with stock suspension with exception of 4" dropped axle. Stock shocks are worn out. I'm told Pete & Jakes and Chassis Engineering both make a front conversion that are different, but haven't heard which is better. Also want to convert the rear, but don't want to weld some street roddie brackets on the housing. Anyone make a good bolt in rear kit? I am new to this and figure there is a wealth of info out there with you guys.
Any help appreciated!
