Hey Ratsun folks. I'm building a '69 521. It's gonna be alot of work, but I'm excited. Always done Chevy's but Datsun was the first truck I ever Loved. Wanna do some different things to it. If I go with an SR or a KA, should I cut the mounts off the original donor car or make my own? Also wondering if its possible to either shorten the steering column or swap it. So many questions. Lets start here.
