Optima mid restoration

[rylance1878]

Hi everyone I used to race optima mids nearly 30 year ago , I loved them in the day so I have just purchased one to do a total restoration on it,can anyone help me in telling me best places to find and buy parts
I then got to decide whether I going to run it
Already wondering whether to go brushed or brushless and whether to do old fashioned paint job as they were or whether to do nice design on it,but that a long way off yet
Anyone who gets in touch is greatly appreciated thanks in advance
